Use
Isocyanates and thioisocyanates, such as Phenyl isocyanate, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Polyurethanes are formed by the condensation reaction of diisocyanates with, for example, ethyl glycol. Phenyl isocyanate, cobalt pentamine triazo perchlorate, and nitrosyl perchlorate mixture was stirred for 2-3 minutes. When the stirring was interrupted, the mixture exploded [Chem. Eng. News 46(8):39. 1968].
