In catalytic decomposition of dimethylhexane-1,6-dicarbamate (HDC) into hexamethylene-1,6-diisocyanate (HDI), Zn-containing homogeneous (i.e., zinc acetate) and heterogeneous (i.e., ZnO) catalysts were active among a number of catalysts tested, due to the
METHOD FOR PREPARING ALIPHATIC DIISOCYANATE

Paragraph 0032, (2014/10/16)
The present invention relates to a method for preparing an aliphatic diisocyanate by pyrolyzing an aliphatic dicarbamate in liquid phase, using a tin (II) or (IV) compound as a catalyst and a zwitterionic compound as a stabilizer, thereby remarkably inhibiting high-boiling by-products and providing the aliphatic diisocyanate with high yield.
