Wong, S. published the artcileCatalysis in competing isocyanate reactions, HPLC of Formula: 2212-32-0, the main research area is butanol phenylisocyanate reaction model polyurethane; chromatog butanol phenylisocyanate reaction; catalysis isocyanate reaction; water phenylisocyanate reaction model polyurethane.

High-performance liquid chromatog. was used to determine the products given by the reaction of phenyl isocyanate  [103-71-9] with butanol  [71-36-3], and the reaction was a model for the main and side reactions occurring in the preparation of polyurethanes. The reaction in the presence of dibutyltin dilaurate  [77-58-7] gave only Bu N-phenylcarbamate (I) [1538-74-5], but PhNHCONPhCO2Bu [21367-12-4] was detected in very early stages of the reaction. The reaction in the presence of N,N’,N”-tris(3-dimethylaminopropyl)hexahydrotriazine  [15875-13-5] gave I and N,N’,N”-triphenylisocyanurate (II) [1785-02-0] simultaneously, but the reaction in the presence of N,N,N’-trimethylaminoethyl ethanolamine  [2212-32-0] gave I and II in sequence. The reaction of Ph isocyanate with water gave mainly PhNHCONHPh [26763-63-3], with 5% PhNHCONPhCO2Bu and PhNHCONPhCONHPh [2645-39-8].

Galla, E. A. published the artcileRIM catalysis and coating interaction, Recommanded Product: N2-(2-Hydroxyethyl)-N1,N1,N2-trimethyl-1,2-ethylenediamine, the main research area is polyurethane reaction injection molding; catalyst polyurethane molding coating; amine catalyst polyurethane molding; triethylenediamine catalyst polyurethane molding.

The use of high-solids Durethane Elastomeric Enamel and Dabco  [280-57-9] catalyst (≤0.15 phr) enables the reaction-injection molding (RIM) of polyurethanes with no adverse effects on the coating. Other amine catalysts, e.g. Dabco T  [2212-32-0], can be added at ≤0.5 phr as cocatalyst with Dabco and Bu2Sn dilaurate [77-58-7]. Moldings catalyzed with >15 phr Dabco were successfully coated by subjecting the part to a high-temperature water rinse or by adding a small amount of acid to the primer.

Galla, E. A. published the artcileRIM catalysis and coating interaction, Formula: C7H18N2O, the main research area is polyurethane molding coating; polymerization catalyst polyurethane coating; triethylenediamine polyurethane coating; molding reaction injection polyurethane.

Reaction-injection molded (RIM) polyurethanes containing ≤0.5 phr triethylenediamine (I) [280-57-9] catalyst and Sn cocatalysts can be coated with com. high-solids coatings (e.g. Durethane 300) or water-based coatings. With an exptl. high-solids Durethane Elastomeric Enamel, I can be used at ≤0.15 phr with no adverse effect, and reactive amine cocatalysts [e.g. Me2NCH2CH2N(Me)CH2CH2OH [2212-32-0]] can be added at 0.5 phr. Parts containing >0.15 phr I can be coated after rinsing with H2O or adding a small amount of acid to the primer. An additive which reacts with I during curing, thus preventing interference with coating without affecting curing rate, can be added to parts containing ≤1.0 phr I.

Zhang, Ruilei published the artcileExcess molar enthalpies for binary mixtures of different amines with water, Computed Properties of 2212-32-0, the main research area is amine molar enthalpy binary mixture water.

The isothermal excess molar enthalpies for binary mixtures of different amines with water were measured with a C-80 Setaram calorimeter. The exptl. results indicate that the excess molar enthalpy is related to the mol. structure. The exptl. excess molar enthalpies were satisfactorily fitted with the Redlich-Kister equation. They were also used to test the suitability of the NRTL model, and the deviations are a little larger than the R-K equation.

Burridge, Kevin M. published the artcileSimple derivatization of RAFT-synthesized styrene-maleic anhydride copolymers for lipid disk formulations, Category: alcohols-buliding-blocks, the main research area is RAFT styrene maleic anhydride copolymer nucleophile derivative lipid disk.

Styrene-maleic acid copolymers have received significant attention because of their ability to interact with lipid bilayers and form styrene-maleic acid copolymer lipid nanoparticles (SMALPs). However, these SMALPs are limited in their chem. diversity, with only Ph and carboxylic acid functional groups, resulting in limitations because of sensitivity to low pH and high concentrations of divalent metals. To address this limitation, various nucleophiles were reacted with the anhydride unit of well-defined styrene-maleic anhydride copolymers in order to assess the potential for a new lipid disk nanoparticle-forming species. These styrene-maleic anhydride copolymer derivatives (SMADs) can form styrene-maleic acid derivative lipid nanoparticles (SMADLPs) when they interact with lipid mols. Polymers were synthesized, purified, characterized by Fourier-transform IR spectroscopy, gel permeation chromatog., and NMR and then used to make disk-like SMADLPs, whose sizes were measured by dynamic light scattering (DLS). The SMADs form lipid nanoparticles, observable by DLS and transmission electron microscopy, and were used to reconstitute a spin-labeled transmembrane protein, KCNE1. The polymer method reported here is facile and scalable and results in functional and robust polymers capable of forming lipid nanodisks that are stable against a wide pH range and 100 mM magnesium.

Romero, Richard R. published the artcileA study of the reaction kinetics of polyisocyanurate foam formulations using real-time FTIR, Name: N2-(2-Hydroxyethyl)-N1,N1,N2-trimethyl-1,2-ethylenediamine, the main research area is polyisocyanurate foam formulation reaction kinetics real time FTIR.

The use of alternative blowing agents for the production of polyisocyanurate (PIR) rigid foam has created a need to better understand how various catalysts participate in isocyanurate formation. The improvement of isocyanate conversion to isocyanurate is one approach to overcome the greater flammability inherent with the use of hydrocarbons. In situ Fourier Transform IR (FTIR) has been used to follow the reaction kinetics of PIR development during foam preparation The activity of amine catalysts for isocyanate conversion is characterized through the use of in situ FTIR. Identification of the reaction products formed from the blowing, gelling, and trimerization reactions provides the opportunity to profile the catalytic effects as the reaction proceeds. Several traditional amine catalysts used by PIR foam manufacturers have been evaluated. The design of catalyst blends in PIR formulation can now be based upon the results of the catalytic activity characterization. In this article, the focus is on understanding the synergies between catalysts used in PIR formulations. Real-time in situ FTIR is the technique of choice for the evaluation of catalysts blends for optimal performance and processing properties.

Capolla, Nadia published the artcileMethylene blue sensitized gelatin used for the fabrication of holographic optical elements in the near-infrared, Recommanded Product: N2-(2-Hydroxyethyl)-N1,N1,N2-trimethyl-1,2-ethylenediamine, the main research area is methylene blue gelatin holog optical element.

In this paper a short review on interconnecting devices using holog. techniques was briefly presented and two particular applications of HOEs designed for the IR wavelength region were discussed. It was then explained why it could be worthwhile to use a recording material sensitive to red wavelengths instead of blue or green wavelengths. Therefore a methylene blue-sensitized gelatin/electron donor system was presented and it was demonstrated that it can record efficient transmission and reflection gratings with a relatively low exposure energy at 633 or 647 nm. An application also shown the qualities of this new recording material, which is believed to be very promising for the fabrication of near-IR holog. components.
