A pure fluorinated aluminophosphate [Al₈P₈O₃₂F₄·(C₃H₁₂N₂)₂(H₂O)₂] (ULM-6) was synthesized via an aminothermal strategy, in which triisopropanolamine (TIPA) was used as the solvent together with the addition of propyleneurea and HF. The ¹³C NMR spectrum demonstrates that 1,3-diaminopropane, the in situ decomposer of propyleneurea, is the real structure-directing agent (SDA) for ULM-6 crystals. The local Al, P, and F environments of the dehydrated ULM-6 were studied by 1-dimensional and 2-dimensional solid-state NMR spectroscopy. The spatial proximities are extracted from ¹⁹F{²⁷Al}, ¹⁹F{³¹P}, ²⁷Al{¹⁹F}, and ³¹P{¹⁹F} rotational-echo double resonance (REDOR) NMR experiments as well as ¹⁹F → ³¹P heteronuclear correlation (HETCOR) NMR and {³¹P}²⁷Al HMQC NMR experiments, allowing a full assignment of all the ¹⁹F, ²⁷Al, and ³¹P resonances to the corresponding crystallog. sites. Also, the structure of ULM-6 is closely related to that of AlPO₄-14. A combination of high-temperature powder XRD, thermal anal., and ¹⁹F NMR reveals that the removal of F atoms at higher temperature is crucial to the phase transformation of ULM-6 to AlPO₄-14. The calcined product shows high CO₂/CH₄ and CO₂/N₂ selectivity with ratios of 15.5 and 29.1 (101 kPa, 25°), resp.

Cao, Zhan-fang published the artcileIn situ nano-Fe₃O₄/triisopropanolamine functionalized graphene oxide composites to enhance Pb²⁺ ions removal, Application of Triisopropanolamine, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2019), 209-217, database is CAplus.

In this work, a kind of magnetic graphene oxide composite material (TI/GO@Fe₃O₄) for Pb²⁺ removal was successfully synthesized through in situ growth method. Briefly, metal ions (Fe³⁺) were fixed on GO surface by oxygen-containing functional groups and acted as growth centers of Fe₃O₄. Furthermore, the surface of GO and Fe₃O₄ nanoparticles were strengthened by the triisopropanolamine and its oxidnation products (TI), which can promote the removal of Pb²⁺ ions. The mass percentage of Fe₃O₄ particles in TI/GO@Fe₃O₄ was 54.31% by EDS datas. Average particle size of TI/GO@Fe₃O₄ is 19.03 nm. The adsorption experiments indicated that the adsorption capacity of TI/GO@Fe₃O₄ can reach 461.00 mg/g under optimized conditions (10 mg TI/GO@Fe₃O₄, 50 mL 500 mg/L Pb²⁺, pH 5.0, 293 K, 120 min). The XPS anal. results indicated that the TI/GO@Fe₃O₄ can adsorb the Pb²⁺ through the complexation between nitrogen and oxygen-containing functional groups and Pb²⁺ ions. Hence, the composite material is a superior material for the adsorption of Pb²⁺. Moreover, the synthesized adsorbent can be recycled by magnet quickly after adsorption.

Mishra, Ratan K. published the artcileEnergy-effective grinding of inorganic solids using organic additives, Application In Synthesis of 122-20-3, the publication is Chimia (2017), 71(7-8), 451-460, database is CAplus and MEDLINE.

We present our research findings related to new formulations of the organic additives (grinding aids) needed for the efficient grinding of inorganic solids. Even though the size reduction phenomena of the inorganic solid particles in a ball mill is purely a phys. process, the addition of grinding aids in milling media introduces a complex physicochem. process. In addition to further gain in productivity, the organic additive helps to reduce the energy needed for grinding, which in the case of cement clinker has major environmental implications worldwide. This is primarily due to the tremendous amounts of cement produced and almost 30% of the associated elec. energy is consumed for grinding. In this paper, we examine the question of how to optimize these grinding aids linking mol. insight into their working mechanisms, and also how to design chem. additives of improved performance for industrial comminution.

Mao, Yong published the artcileEffect of TIPA/TEA combined grinding aid on the behavior of quartz flotation in DDA system, Category: alcohols-buliding-blocks, the publication is Powder Technology (2022), 117570, database is CAplus.

In this paper, different dosages of TIPA, TEA and their combined grinding aid were added to the process of quartz grinding and their influence on the grinding efficiency and flotation recovery in DDA system was investigated. From the grinding and flotation experiments, It can be known that the effect of the combined grinding aid was better than that of a single reagent, which can not only significantly improve the grinding efficiency of quartz, but also increase the recovery of quartz from flotation. Based on the results of FT-IR spectroscopy, XPS anal., quantum chem. and solution chem. calculations, it can be seen that the hydroxyl groups in the TIPA/TEA combined grinding aid formed hydrogen bonds with O on the (101) surface of quartz, while collector DDA was mainly electrostatically adsorbed on the surface of quartz with neg. potential, and the introduction of combined grinding aid improved the adsorption of DDA, the grinding aid and collector played a synergistic role instead of competitive adsorption. The detection of contact angle and surface tension showed that the combined grinding aid can improve the hydrophobicity of quartz, reduce the surface tension and CMC value of DDA, and enhance the dispersibility of quartz, therefore, it can increase the recovery of quartz from flotation.

Lu, Xiaolei published the artcileStudy on the hydration product of ettringite in cement paste with ethanol-diisopropanolamine, SDS of cas: 122-20-3, the publication is Journal of Thermal Analysis and Calorimetry (2020), 139(2), 1007-1016, database is CAplus.

A review. Ettringite (AFt) is a very important hydration product of hardened cement pastes in the early stage. The effect of ethanol-diisopropanolamine (EDIPA) on the formation and transform process of AFt in cement pastes was systematically investigated in this paper. The results indicate that the AFt content in hardened cement pastes notably decreases due to the inhibition effect of EDIPA on the dissolution of gypsum. In addition, EDIPA promotes the transformation of AFt into calcium monosulfoaluminate hydrate and considerably alters the morphol. of AFt crystals from the acicular crystals to stubby rods crystals. The mechanism of the formation of EDIPA-Ca²⁺ complex by the interaction between Ca²⁺ in ettringite and the oxygen atoms in EDIPA mol. was proposed. EDIPA-Ca²⁺ complex can slow down or prevent the crystal growth process of AFt and lead to altering the morphol. of AFt crystals.

Huang, Hong published the artcileSulfate adjustment for cement with triisopropanolamine: Mechanism of early strength enhancement, Application of Triisopropanolamine, the publication is Construction and Building Materials (2018), 516-522, database is CAplus.

This paper investigated the impacts of sulfate adjustment on strength, hydration and the microstructure of cement with triisopropanolamine (TIPA) to propose the mechanism of early strength enhancement from the microscopic point of view. The results showed that a single addition of TIPA was only good for cement strength promotion on 28 days. While an appropriate sulfate adjustment (∼0.6% in SO₃) was effective in enhancing the 1 day and 3 days strengths of cement with TIPA. When more sulfate was introduced, a clear delay in the AFt to AFm conversion and a steady increase of heat release could be observed during the early hydration of cement. QXRD analyses revealed that TIPA was able to promote the hydration of intermediate phases, particularly C₄AF, resulting in the fast formation of aluminate hydrates. The increased sulfate in cement with TIPA not only stabilized AFt formation but also promoted the silicate reaction in the early stages. SEM confirmed that the single addition of TIPA promoted the formation of coarse AFm clusters filling the pores of hardened cement paste. The increased sulfate restored the formation of fine AFt particles, which further refined the microstructure of the paste. Since the addition of TIPA and the adjustment of sulfate altered the hydration kinetics of intermediate phases, different aluminate hydrates intermixing with C-S-H could also be observed

Yang, Songge published the artcileImpact of four kinds of alkanolamines on hydration of steel slag-blended cementitious materials, HPLC of Formula: 122-20-3, the publication is Construction and Building Materials (2017), 655-666, database is CAplus.

The impact on hydration of four kinds of alkanolamines (triethanolamine (TEA), triisopropanolamine (TIPA), diethanol-isopropanolamine (DEIPA) and methyldiethanolamine (MDEA)) in a steel slag cementitious system was reviewed. Isothermal calorimetry studies provided information on the hydration heat release rate and the cumulative energy released by blend cement systems. Mortar strength, quant. X-ray diffractometry, mercury intrusion pore size distribution anal., SEM and thermogravimetric anal. were used to analyze the mechanism of strength enhancement and micro-structure of hydrates that were impacted by alkanolamines. Alkanolamines prolonged the hydrated induction period in the steel slag-cement system, and enhanced the second exothermic peak of hydration at dosages of 0.01%, 0.03% and 0.05%. The second hydration rate was decreased by TEA, DEIPA and MDEA, and increased by TIPA at alkanolamine dosages of 0.1% and 0.2%. The compressive strength and non-evaporable water content were enhanced by the four types of alkanolamines (dosage of 0.03%) at 3 d, 7 d and 28 d, which allowed TEA and DEIPA to contribute to strength development and the hydration reaction over TIPA and MDEA. The CH content, porosity and pore size were decreased by alkanolamines at different ages. Alkanolamines promoted the formation of ettringite and an alumina-ferric oxide-monosulfate phase, and the C-S-H morphol. was also changed by different kinds of alkanolamines.

Wang, Xueli published the artcileEffect of amino-ternary alcohol on hydration of blend cementitious system with steel slag and granulated blast furnace slag, Recommanded Product: Triisopropanolamine, the publication is Guisuanyan Xuebao (2017), 45(2), 206-211, database is CAplus.

The influence of amino-ternary alc. (ATA) on the strength development and hydration of composited cementitious system incorporated with steel slag-granulated blast furnace slag (GBFS) was investigated. The mech. and hydration properties of steel slag-GBFS blend cementitious system in the presence of triethanolamine (TEA), triisopropanolamine (TIPA) and diethanol-isopropanolamine (DEIPA) were analyzed by mortar experiment, hydration heat release, X-ray diffraction (XRD), differential scanning calorimetry-thermogravimetry (DSC-TG) and SEM (SEM), resp. The results show that the promoting effect of ATA on the hydration of steel slag-GBFS cementitious system is related to the numbers of Me on the branched chain of ATA. A few numbers of Me can favor the strength development. The compressive strength of blend cementitious system is promoted by ATA, among which TEA leads to the maximum compressive strength at different ages. The addition of ATA can enhance the hydration of steel slag and GBFS via increasing the heat flow at early age and decreasing the content of portlandite (CH) to form a more compacted structure. The addition of ATA has a pos. effect on the strength development of composited cementitious system.

Li, Feng published the artcileAlkanolamines as activators in no-clean flux systems: investigation of humidity robustness and solderability, Recommanded Product: Triisopropanolamine, the publication is Journal of Materials Science: Materials in Electronics (2021), 32(4), 4961-4981, database is CAplus.

This paper systematically investigates the humidity robustness and solderability of five alkanolamines used as activators in flux systems, and their effect was assessed along with the influence of soldering temperature Electrochem. impedance spectroscopy and chronoamperometry techniques were used to obtain a better understanding of water adsorption, absorption, and protonation tendencies of alkanolamine candidates. Potentiodynamic polarization, hot plate spreading test, and wetting balance test were adapted for the etching ability and solderability evaluation. Thermal degradation of alkanolamine compounds was analyzed using thermogravimetric anal. (TGA) and Fourier-transform IR spectroscopy (FT-IR). The combined results indicate a strong water absorption and protonation of diethanolamine (DEA), triethanolamine (TEA), and triisopropanolamine (TIPA), rendering them not reliable and not feasible as activators. Poor solderability of alkanolamine-based fluxes was inferred based on their thermal degradation behavior and poor oxide removal ability under the soldering conditions.

Tian, Zhenyu published the artcileSuspect and Nontarget Screening for Contaminants of Emerging Concern in an Urban Estuary, Safety of Triisopropanolamine, the publication is Environmental Science & Technology (2020), 54(2), 889-901, database is CAplus and MEDLINE.

This study used suspect and nontarget screening with high-resolution mass spectrometry to characterize the occurrence of contaminants of emerging concern (CECs) in the nearshore marine environment of Puget Sound (WA). In total, 87 non-polymeric CECs were identified; those confirmed with reference standards (45) included pharmaceuticals, herbicides, vehicle-related compounds, plasticizers, and flame retardants. Eight polyfluoroalkyl substances were detected; perfluorooctanesulfonic acid (PFOS) concentrations were as high as 72-140 ng/L at one location. Low levels of methamphetamine were detected in 41% of the samples. Transformation products of pesticides were tentatively identified, including two novel transformation products of tebuthiuron. While a hydrodynamic simulation, anal. results, and dilution calculations demonstrated the prevalence of wastewater effluent to nearshore marine environments, the identity and abundance of selected CECs revealed the addnl. contributions from stormwater and localized urban and industrial sources. For the confirmed CECs, risk quotients were calculated based on concentrations and predicted toxicities, and eight CECs had risk quotients >1. Dilution in the marine estuarine environment lowered the risks of most wastewater-derived CECs, but dilution alone is insufficient to mitigate risks of localized inputs. These findings highlighted the necessity of suspect and nontarget screening and revealed the importance of localized contamination sources in urban marine environments.
