Organic isocyanates are prepared by thermal decomposition of N,N'-disubstituted allophanic acid esters in an organic carbonate at from 150 DEG to 400 DEG C. The isocyanates obtainable by this process are valuable starting materials for the preparation of crop protection agents, pesticides, dyes, synthetic resins, plastics, textile waterproofing agents, detergents, bleaching agents and adhesives. |
