Title: Preparing cuprous oxide
IPC: B01J19/00
Filed: 1971-03-25
Abstract: 1387260 Cuprous oxide KODAK Ltd 23 March 1972 [25 March 1971] 7841/71 Heading C1A Cuprous oxide is prepared by a process comprising reacting complex cuprous anions with hydroxyl ions in an aqueous medium while maintaining the pH at the point of reaction at a level between 9 and 12 (at which formation of new nuclei for precipitation is inhibited) thereby forming cuprous oxide as substantially unaggregated particles of controllable size. Suitably, an aqueous solution containing complex cuprous anions is mixed with an aqueous suspension of a metal hydroxide which has a solubility in water at 25‹ C. of between 3À5 x 10<SP>-2</SP> and 1À0 Î 10<SP>-4</SP> moles/litre, e.g. magnesium, calcium or strontium hydroxide. The preferred complex curpous anions may be of the formula Cu(Hal)- 2 , where Hal represents a halide ion, e.g. chloride or bromide, which may be derived from a complex halide of copper (I) and magnesium, calcium or strontium, itself obtainable by dissolving cuprous oxide and magnesium, calcium or strontium halide in a halide acid H(Hal). The hydroxide suspension may comprise in solution a halide of magnesium, calcium or strontium and be prepared by adding the stoichiometric amount or less of alkali metal hydroxide to a solution of the other metal halide. Precipitation of cuprous oxide is preferably performed in the presence of cuprous oxide seeds. These seeds may be prepared by precipitation in the presence of a peptizing agent, e.g. a water-soluble polymer described in U.S. Specification 3,615,624 and preferably adding a solution of cuprous chloride, sodium bromide and ascorbic acid to an aqueous solution of NaOH containing poly 3 - thiapentylacrylate - Co - 3- acryloyloxypropane - 1 - sulphonic acid sodium salt, yielding a fine grain dispersion of Cu 2 O seeds in which the cuprous oxide precipitation is then effected as above. The precipitate may be allowed to ripen yielding grains of size 0À2-7 Á.
