Reacts with water to form CO2
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
Isocyanates and thioisocyanates, such as 1,1-METHYLENE BIS(4-ISOCYANATOCYCLOHEXANE), 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. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer(1969)].
10.4 Conditions to avoid
no data available
10.5 Incompatible materials
Substance reacts with water. ...Dicyclohexylmethan-4,4'-diisocyanate reacts in comparison to hexamethylene diisocyanate very slowly with water and slowly with alcohols or amines; normally the reaction must be catalyzed with metal compounds.
