In this study, the authors focused on obtaining polysulfone-polyurethane (PSF-PUR) blend partly degradable hollow fiber membranes (HFMs) with different compositions while maintaining a constant PSF:PUR = 8:2 weight ratio. It was carried out through hydrolysis, and evaluation of the properties and morphol. before and after the hydrolysis process while maintaining a constant cut-off. The obtained membranes were examined for changes in ultrafiltration coefficient (UFC), retention, weight loss, morphol. assessment using SEM and MeMoExplorer Software, as well as using the Fourier-transform IR spectroscopy (FT-IR) method. The results of the study showed an increase in the UFC value after the hydrolysis process, changes in retention, mass loss, and FT-IR spectra. The evaluation in MeMoExplorer Software showed the changes in membranes’ morphol. It was confirmed that polyurethane (PUR) was partially degraded, the percentage of ester bonds has an influence on the degradation process, and PUR can be used as a pore precursor instead of superbly known polymers. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Safety of Pentane-1,5-diol

Abranches, Dinis O.; Soares, Bruna P.; Ferreira, Ana M.; Shimizu, Seishi; Pinho, Simao P.; Coutinho, Joao A. P. published an article in 2022, the title of the article was The impact of size and shape in the performance of hydrotropes: a case-study of alkanediols.Related Products of 111-29-5 And the article contains the following content:

Inspired by the recently proposed cooperative mechanism of hydrotropy, where water mols. mediate the aggregation of hydrotrope around the solute, this work studies the impact of apolar volume and polar group position on the performance of hydrotropes. To do so, the ability of two different families of alkanediols (1,2-alkanediols and 1,n-alkanediols) to increase the aqueous solubility of syringic acid is initially investigated. Interestingly, it is observed that in the dilute region (low hydrotrope concentration), the relative position of the hydroxyl groups of the alkanediols does not impact their performance. Instead, their ability to increase the solubility of syringic acid correlates remarkably well with the size of their alkyl chains. However, this is not the case for larger hydrotrope concentrations, where 1,2-alkanediols are found to perform, in general, better than 1,n-alkanediols. These seemingly contradictory findings are reconciled using theor. and exptl. techniques, namely the cooperative model of hydrotropy and chem. environment probes (Kamlet-Taft and pyrene polarity scales). It is found that the number of hydrotropes aggregated around a solute mol. does not increase linearly with the apolar volume of the former, reaching a maximum instead. This maximum is discussed in terms of competing solute-hydrotrope and hydrotrope-hydrotrope interactions. The results suggest that hydrotrope self-aggregation is more prevalent in 1,n-alkanediols, which neg. impacts their performance as hydrotropes. The results reported in this work support the cooperative model of hydrotropy and, from an application perspective, show that hydrotropes should be designed taking into consideration not only their apolar volume but also their ability to stabilize their self-aggregation in water, which neg. impacts their performance as solubility enhancers. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Related Products of 111-29-5

Hayashi, Mikihiro; Obara, Haruna; Miwa, Yohei published an article in 2021, the title of the article was Design and basic properties of polyester vitrimers combined with an ionomer concept.Reference of Pentane-1,5-diol And the article contains the following content:

Vitrimers are a novel class of crosslinked materials containing associative bond exchange properties. Here we demonstrate the preparation of vitrimers with ionic components to investigate the effects of ion-rich domain formation on vitrimer properties. An amorphous polyester that bears COOH side groups was synthesized, and some fraction of COOH was neutralized with Zn2+. The residual non-neutralized COOH was reacted with diepoxy crosslinkers, resulting in a network with ester bonds, OH groups, and COOH groups neutralized with Zn2+. The sample was further thermally annealed to induce aggregation of Zn2+ ionic groups. The aggregated Zn2+ groups in the network remained active for trans-esterification-based bond exchange, wherein the degree of ion aggregation can be a factor in tuning the bond-exchange properties. The present study provides some important knowledge on the design of new mol. systems of vitrimers with tunable bond exchange properties.

A review. The depletion of fossil resources in the near future and the need to decrease greenhouse gas emissions lead to the investigation of using alternative renewable resources as raw materials. One of the most promising options is the conversion of lignocellulosic biomass (like forestry residues) into bioenergy, biofuels and biochems. Among these products, the production of intermediate biochems. has become an important goal since the petrochem. industry needs to find sustainable alternatives. In this way, the chem. industry competitiveness could be improved as bioproducts have a great potential market. Thus, the main objective of this review is to describe the production processes under study (reaction conditions, type of catalysts, solvents, etc.) of some promising intermediate biochems., such as; alcs. (1,2,6-hexanetriol, 1,6-hexanetriol and pentanediols (1,2 and 1,5-pentanediol)), maleic anhydride and 5-alkoxymethylfuran. These compounds can be produced using 5-hydroxymethylfurfural and/or furfural, which they both are considered one of the main biomass derived building blocks.

On April 9, 2020, Yang, Xingchuan; Wei, Genlei; Chen, Xiangmeng; Xu, Li; Liu, Guoji published an article.Application of 111-29-5 The title of the article was Liquid-Liquid Equilibrium Measurement and Correlation for the Ternary Systems (Dimethyl Succinate + 1,4-Butanediol)/(Dimethyl Glutarate + 1,5-Pentanediol)/(Dimethyl Adipate + 1,6-Hexanediol) + Water at Different Temperatures. And the article contained the following:

Liquid-liquid equilibrium (LLE) data for esters + diols + water ternary systems were measured at 101.3 kPa at four different temperatures, namely, 293.15, 303.15, 313.15, and 323.15 K. The Othmer-Tobias equation and the Hand equation were applied to examine the reliability of the LLE data in which both regression coefficients were higher than 0.98. The calculated distribution coefficients and separation factors were larger than 1, which means that it is feasible to extract the diols from the corresponding ester with water. In addition, NRTL and UNIQUAC models were applied to correlate the exptl. data, and the binary interaction parameters were obtained. The calculated root-mean-square deviation values show that both models are in good agreement with the exptl. data. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Application of 111-29-5

And the article contained the following:

The optical properties of glassy liquid crystals (GLC’s) designed to provide high resistance to laser-induced damage are explored. GLC’s readily enable freezing of the anisotropic ordering of liquid crystals into the glassy state. This solidity avoids issues of fluid leakage while providing mech. robustness and the promise of single-substrate coatings or stand-alone films of nanometer to micrometer thicknesses. A series of three increasingly saturated GLC’s were synthesized and tested for their thin-film (hundreds of nanometers to tens of micrometers) high-peak-power laser-damage resistance with nanosecond pulses at 1053, 532, and 351 nm, as well as their durability under continuous-wave, broadband UV illumination. The GLC’s with higher degrees of saturation demonstrated high resistance to laser-induced damage, extending from the near-IR to the UV spectral region. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Computed Properties of 111-29-5

The Article related to alc ether platinum catalyst hydrogenolysis kinetics mechanism, Physical Organic Chemistry: Oxidation-Reduction, Including Dehydrogenation and Hydrogenolysis and other aspects.Formula: C5H12O2

On August 1, 2020, Aihara, Takeshi; Miura, Hiroki; Shishido, Tetsuya published an article.Formula: C5H12O2 The title of the article was Investigation of the mechanism of the selective hydrogenolysis of C-O bonds over a Pt/WO3/Al2O3 catalyst. And the article contained the following:

The hydrogenolysis of various polyols and ethers over a Pt/WO3/Al2O3 catalyst was investigated. The hydrogenolysis rate of a C-O bond at a secondary carbon was higher than that at a primary carbon, indicating that a hydroxyl (OH) group at a primary carbon played an important role in the dissociation of a C-O bond. Moreover, the dissociation position of the C-O bond in alcs. and ethers strongly depended on the stability of the carbocation intermediate, and hydrogenolysis via a secondary carbocation as an intermediate proceeded preferentially to that via a primary carbocation. The kinetics of the hydrogenolysis of C3 polyols were also investigated. The reaction orders with respect to the concentrations of glycerol, 1,2- and 1,3-propanediol were almost the same. In contrast, different reaction orders with respect to the H2 pressure were observed for the hydrogenolysis of C3 polyols with or without vicinal OH groups, indicating that the dissociation of a C-O bond at primary and secondary carbons proceeded via completely different mechanisms. These investigations suggested that both the structure and position of a substrate on the catalyst surface must be controlled for highly selective hydrogenolysis. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Formula: C5H12O2
