Triethylenediamine ( CAS: 280-57-9 )









Triethylenediamine

Tianjin Zhongxin Chemtech Co., Ltd

(1)It is neutralized by carboxylic acid and dissolve in dipropylene glycol ,used as a catalyst or cross-linker in urea reaction as well as urethane reaction in the production of polyurethane foams, elastomers and adhesives. It has strong catalyst effect for the reactions of alicyclic and aliphatic isocyanates whereas less active in aromatic isocyanates etc.
(2) As basic reagents,bases activation of deprotonation is the first step in the synthesis. The strength of basicity, nucleophilicity, steric hindrance or solubility are the factors to select reagents for the best results in the chemical reactions : alkylation, tautomerization, dehydrohalogenation, saponification, acylation michael-addition, esterification, silylations, aldol-condensation, eliminations, and cyclization etc.
