1,3-BIS(ISOCYANATOMETHYL)CYCLOHEXANE Chemical Properties,Usage,Production

Uses

1,??3-??Bis(isocyanatomethyl??)??cyclohexane (Mixture of Cis and Trans) is a reactant used in the synthesis of ionic polyurethanes as a family of poly(ionic) liquids which efficiently can capture CO2 in an effort to curb emissions.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.

Reactivity Profile

Isocyanates and thioisocyanates, such as 1,3-BIS(ISOCYANATOMETHYL)CYCLOHEXANE, 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)].
