The production of hydrocarbons bromo (chlorine) and hydrocarbons, bromo fluorinated thus obtained (chloro)

摘要

P a. the invention relates to the production of hydrocarbons bromo (fluoro chloro) by substitution of chlorine, bromine in chlorinated hydrocarbons, corresponding to the means of hydrogen in the gaseous phase, to tempémture. / p & & p & b. the reaction is carried out at 100 - 500°C, in the presence of a catalyst containing active charcoal, silica gel, activated alumina, bromides of certain metals or mixtures of said compounds. / p & & p & c. the process is particularly useful for the production of hydrocarbons bromo (fluoro chloro) containing 1 to 3 carbon atoms in the molecule. It is possible to obtain high yields. / p
