Reactivity Profile · 1 Eintrag

Isocyanates and thioisocyanates, such as 1,5-NAPHTHALENE DIISOCYANATE, 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)].

Chemical DangersDecomposes on heating. This produces toxic fumes of nitrogen oxides, carbon monoxide, isocyanates and hydrogen cyanide. Reacts with acids, alcohols, amines, bases, strong oxidants, strong reducing agents and water.
Flammable LimitsCombustible Solid
Packaging and LabellingDo not transport with food and feedstuffs.
Air and Water ReactionsNo rapid reaction with air. No rapid reaction with water.
