Abstract

PURPOSE: To prepare the title compound industrially, useful as a raw material for polyurethanes having excellent hardness, etc., by the reaction of 4,4'-diisocyanate-dicyclohexylmethane isomer mixture with hydrogen halide at low temperature, followed by the decomposition of the resulting precipitate on heating.
