ABSTRACT:
Copper(II) hydroxide is produced by a reaction of copper oxychloride in an aqueous suspension with alkali hydroxide or alkaline earth metal hydroxide in the presence of a stabilizing agent and the product is separated and washed. To improve the stability of the copper hydroxide and to avoid a black coloring by copper oxide, inorganic silicon compounds which contain hydroxyl groups (SiOH) in the molecules or form such groups in an aqueous medium are added to the suspension. It is desirable to use particulate solid silicic acids or silicic acids which are soluble in water or colloidally dissolved.
