Epoxy vitrimers with a covalently bonded tertiary amine as catalyst of the transesterification reaction
(Pergamon-Elsevier Science Ltd, 2019-02)
Tertiary amines are one of the typical catalysts used to accelerate transesterification reactions in epoxy vitrimers. Instead of adding a tertiary amine (e.g. tributylamine, TBA) to the initial formulation, secondary (e.g. ...
Selective one-pot synthesis of asymmetric secondary amines via N-alkylation of nitriles with alcohols
(Academic Press Inc Elsevier Science, 2019-10)
The synthesis of asymmetric secondary amines (ASA) is commonly achieved by N-alkylation of primaryamines with alcohols. Here, we investigated the ASA synthesis via the direct amination of alcohols withnitriles, which avoids ...
SYNTHESIS, THERMAL STUDIES AND CONVERSION DEGREE OF DIMETHACRYLATE POLYMERS USING NEW NON-TOXIC COINITIATORS
(Soc Brasileira Quimica, 2017-05-01)
The aim of this paper is to replace toxic coinitiators (tertiary amines) by non-toxic compounds such as glycerol and inositol (polyalcohol) in dimethacrylate resins. For this purpose, mid infrared spectroscopy (MIR) was ...
Extraction of mo (vi) with tertiary amines in a solid-supported liquid membrane reactor
(SOCIEDAD CHILENA DE QUÍMICA, 2001)
Kinetics of the epoxy-thiol click reaction initiated by a tertiary amine: Calorimetric study using monofunctional components
(Elsevier Science, 2015-08-08)
An analysis of the kinetics of the epoxy–thiol reaction in a model stoichiometric system of monofunctional reagents, 3-mercaptopropionate (BMP) and phenylglycidylether (PGE) is reported. Benzyldimethylamine (BDMA) was ...
Radical amination with trimethylstannylated benzophenone imine
(American Chemical Society, 2010-04)
Intermolecular radical amination reactions of various primary, secondary, and tertiary alkyl radicals by using trimethylstannylated benzophenone imine A as a novel radical acceptor to provide imines of type B are described. ...
The use of water soluble tertiary amine reagent for solubilization and metal determination in fish muscle tissue
(2005)
A extração de metais com aminas terciárias solúveis (reagente CFA-C) assistida por ultra-som e em presença de peróxido de hidrogênio foi usada para solubilização de metais em amostras de peixe. Duas espécies de peixes de ...
Cross-Dehydrogenative Coupling of Tertiary Amines and Terminal Alkynes Catalyzed by Copper Nanoparticles on Zeolite
(Wiley, 2015-10)
A wide range of catalysts based on supported copper nanoparticles have been prepared and tested in the cross-dehydrogenative coupling of tertiary amines and terminal alkynes. Copper nanoparticles on zeolite Y were found ...
Extraction of Mo (VI) with tertiary amines in a solid-supported liquid membrane reactor
(SOCIEDAD CHILENA DE QUIMICA, 2001-06)
This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the study of recovery and enrichment of molybdenum with Alamine 336 (a long chain tertiary amine) from acid ...
