Method for preparing aliphatic diisocyanate
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.
