1,3-Phenylene diisocyanate Chemical Properties, Uses, Production
Chemical Properties
White to off-white fused solid
Uses
1,3-Phenylene Diisocyanate is a reagent used in the synthesis of polyurethane materials and other thermoplastics.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.
Reactivity Profile
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.
