ORGANIC ISOCYANATE REACTION PROCESS BY CATALYTIC ACTION |
摘要 |
<p>Polymerization and condensation reactions of organic isocyanates are catalytically promoted by the use of N-hydroxyalkyl quaternary ammonium carbonylate salts, particularly in the production of polyisocyanurates and polyurethanes. Among the exemplary preferred catalysts are N-hydroxypropyl trimethyl ammonium salts of carboxylic acids such as those of formic and acetic acids and of fatty acids such as hexanoic and octanoic acids and the like.</p> |
