Katalysator for oksiklorering av etylen, fremgangsmåte for fremstilling av disse, og fremgangsmåte for slik oksiklorering

摘要

Catalysts for the oxichlorination of ethylene to 1,2-dichlorethane, comprising copper chloride as a main component, in the form of hollow cylindrical granules having at least three through holes, obtained by compression forming by using, for lubrication, a lubricant placed on the walls of the forming chamber and on the plungers of the mold.
