VERFAHREN ZUR HERSTELLUNG VON GEMISCHEN VON 1-MONOHALOGENIERTEN ISOCYANATEN UND 1,2-UNGESAETTIGTEN ISOCYANATEN

摘要

1-Monohalogenated isocyanates, and a process for the preparation of mixtures of 1-monohalogenated isocyanates and 1,2-unsaturated isocyanates by reacting 1-monohalogenated carbamic acid halides or isocyanates with a halogen-free isocyanate or diisocyanate or by reacting 1,2-unsaturated isocyanates with a carbamic acid halide or a bis-carbamic acid halide. The 1,2-unsaturated isocyanates and 1-monohalogenated isocyanates prepared according to the invention are valuable starting materials for the preparation of pest control agents, dyes, drugs, water-repellent textile finishes, detergents, plastics, bleaches and adhesives.
