1,3-PHENYLENE DIISOCYANATE C화학적 특성, 용도, 생산
화학적 성질
White to off-white fused solid
반응 프로필
Isocyanates and thioisocyanates, such as 1,3-PHENYLENE 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)].
Safety Profile
A sensitizer at very low
concentrations. Deadly poison by
intravenous route. When heated to
decomposition it emits toxic fumes of NOx
and CN-. See also ESTERS.
