Abstract

Abstract:

The two isomers of isophrone diisocyanate (IPDI) were characterized by \{\}\+1H and \{\}\+\{13\}C NMR spectroscopy. The stability of the compounds at different temperatures was studied by \{\}\+\{13\}C NMR. The results show that the chemical shift and the peak area of the two isomers didn't change at 40～80 ℃ so that it may be concluded that the two isomers were stable in this temperature range.

Key words: NMR, isophrone diisocyanate, isomer, heat-stability
