Title:
PRODUCTION METHOD FOR ISOCYANATE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/100971
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method that makes it possible to safely and efficiently produce an isocyanate compound. This production method for an isocyanate compound is characterized by including: a step for irradiating a halomethane with high-energy light in the presence of oxygen at a temperature of no higher than 15̊C; and a step for adding an amine compound and reacting without radiating the high-energy light.
