Title (EN) CATALYTIC DEHYDROCHLORINATION OF HYDROCHLOROFLUOROCARBONS
(FR) DÉSHYDROCHLORATION CATALYTIQUE D'HYDROCHLOROFLUOROCARBURES
Abstract: front page image
(EN)A dehydrochlorination process is disclosed. The process involves contacting RfCHClCH2Cl with a catalyst in a reaction zone to produce a product mixture comprising RfCCl=CH2, wherein said catalyst comprises MY supported on carbon, and wherein Rf is a perfluorinated alkyl group, M = K, Na or Cs, and Y = F, Cl or Br.
(FR)L'invention concerne un procédé de déshydrochloration. Ce procédé comprend la mise en contact de RfCHClCH2Cl avec un catalyseur dans une zone réactionnelle afin d'obtenir un mélange de produits comprenant du RfCCl=CH2, ledit catalyseur comprenant du MY supporté sur du charbon et Rf étant un groupe alkyle perfluoré, M = K, Na ou Cs, et Y = F, Cl ou Br.
