NCIt related terms : TOLUENE DIISOCYANATE (MIXED ISOMERS);
NCIt definition : A synthetic mixture of the 2,4- and 2,6-isomers is a volatile, colorless to pale yellow
liquid that is soluble in many organic solvents. These isomers are used primarily
in the synthesis of polyurethane foams. When heated to decomposition, toluene diisocyanate
emits toxic fumes of cyanides and nitrogen oxides. Exposure of humans to toluene diisocyanate
causes tissue irritation, especially to the mucous membranes, and can produce severe
respiratory problems. These isomers are reasonably anticipated to be human carcinogens.
