Abstract
Способ получения трихлорэтилена дегидрохлорированием тетрахлорэтана при повышенной температуре в присутствии амина, отличающийся тем, что, с целью упрощения технологии, процесс проводят в присутствии водного раствора гидроокиси кальция при температуре 60 - 70C, а в качестве амина используют полиамины общей формулы:NН-СН-СН(NН-СН-СН)NН,где n = 1 - 4, в количестве 0,1 - 1,0 вес.%.The method of obtaining trichlorethylene by dehydrochlorinating tetrachloroethane at elevated temperature in the presence of amine, characterized in that, in order to simplify the process, the process is carried out in the presence of an aqueous solution of calcium hydroxide at a temperature of 60 - 70 ° C, and polyamines of the general formula: NH-CH-CH (NH-CH-CH) NH, where n = 1-4, in an amount of 0.1 - 1.0 wt.%.
