Abstract: 1,2-Dichloroethane is prepared by oxychlorination of ethylene in the presence of a catalyst which contains, on a conventional carrier, copper(II) chloride in a concentration such that the amount of copper ions is from 1 to 20% by weight, based on the total weight of the catalyst, by a process in which the catalyst is obtained by impregnating the carrier with an aqueous solution which contains copper(II) chloride and hydrogen chloride in amounts such that the weight ratio of copper ions to hydrogen chloride is from 13:1 to 130:1.

Abstract: A process for the manufacture of acicular magnetic iron oxide consisting of a core of gamma-iron(III) oxide and a ferrite shell which contains, based on the total amount of magnetic material, from 0.2 to 12 percent by weight of cobalt(II) ions and from 0.1 to 15 percent by weight of iron(II) ions, wherein a solution containing cobalt(II) hydroxide and iron(II) hydroxide is applied to acicular gamma-iron(III) oxide particles and the latter are heated at 100 DEG -220 DEG C.
