| Abstract：The vinylidene chloride was produced from 1,1,2-trichlorethane. The process for the production of 1,1-dichloro-2-nitroethylene which comprises reacting vinylidene chloride with nitric acid and hydrogen chloride was researched. The reaction temperature, operation time, molar ratio of 1,1,2-trichlorethane and sodium hydroxide, and molar ratio of vinylidene chloride and nitric acid, and hydrogen chloride were discussed. The optimum operation conditions were as follow: at the first step,reaction temperature 65... |
