METHOD FOR PRODUCING 2,2-DIFLUORETHYLAMINE FROM 2,2-DIFLUOR-L-CHLORETHANE AND AMMONIA.

摘要

The invention relates to a method for producing 2,2-difluorethylamine, having the following steps: (i) mixing 2,2-difluor-l-chlorethane and gaseous, liquid, or supercritical ammonia in a pressure-stable closed reaction vessel at a pressure ranging from 10 to 180 bar; (ii) reacting the reaction mixture at a reaction temperature ranging from 80 °C to 200 °C; and (iii) relieving the pressure on the reaction mixture and isolating 2,2-difluorethylamine.
