Title: Process for manufacturing fungicidal tribasic copper chloride
IPC: C01G3/06
Filed: 1960-02-23
Abstract: Tribasic copper chloride, CuCl2.3Cu(OH)2, is prepared by passing preheated air through an aqueous solution of copper chloride in the presence of the metallic copper and a catalyst selected from ammonium hydroxide and carbonate, sodium hydroxide and carbonate and urea. The copper chloride is prepared by reacting a portion of the tribasic copper chloride product with hydrochloric acid and recycling.  At least 66% by weight of the tribasic copper chloride product has a particle size less than 3 microns.  According to an example, copper bars were stacked in a tall vertical reaction vessel provided at its base with hot air distributers.  Tribasic copper chloride from a previous operation was placed in the reactor together with hydrochloric acid to form copper chloride solution which was diluted and reacted with hot air, after the addition of 0,05 to 0,15% of sodium carbonate in aqueous solution based on the copper chloride in the reactor. When the reaction was substantially complete, sodium carbonate was added to neutralize any residual copper remaining as copper chloride in the solution and the liquor containing tribasic copper chloride in suspension was filtered and the product washed and dried.ALSO:Tribasic copper chloride, CuCl2.3Cu(OH)2, 66% by weight of which has a particle size below 3 microns (see Group III) is employed as a fungicide in admixture with a carrier or, if desired in admixture with lead arsenate, calcium arsenate, rotenone, pyrethrum, DDT, BHC, "Chlordane" (Registered Trade Mark), toxaphene, parathion, "Malathion" (Registered Trade Mark), aldrin, dieldrin, sulphur, lime and winter oils.
