Abstract
Colloidal solutions of copper, silver, mercury, cerium, arsenic and antimony, or of their insoluble compounds, are prepared by treating these metals or their compounds for some time at temperatures above 100 DEG C. with waste sulphite cellulose liquor or waste soda cellulose liquor. The metal or its insoluble compound in the powder form may comprise the starting material; or a soluble salt of the metal may be added to the cellulose waste liquor and the metal or its insoluble compound formed therein during the process either by the addition of precipitants, such as alkali, or by the reducing action of the cellulose waste liquor itself, with or without other reducing agents, such as sulphuretted hydrogen. The colloidal product may be precipitated or purified in any known manner and utilized in medicine, veterinary surgery, tanning, the preparation of cosmetics, for the protection of plants, and the impregnation of wood or fabric. The colloidal products may be employed per se, or in conjunction with oil, resin and other organic emulsions, or with the addition of colloids or filling substances. In the case of plant protection, such materials as aluminium hydrate, aluminium sulphate, gypsum, barium carbonate, lime, or copper-lime mixtures may be added to the colloidal products. According to the examples:-(1) colloidal mercury is prepared by heating mercuric chloride with purified waste sulphite cellulose liquor, preferably with addition of caustic soda or potash; or by heating mercuric oxide with the lignine substances extracted from waste sulphite cellulose liquid in the known way; (2) copper sulphate, on heating with waste sulphate cellulose liquor and soda lye, is converted first into colloidal copper protoxide and then into colloidal copper; a similar result is obtained by heating powdered copper oxide with a mixture of waste soda cellulose liquor and waste sulphite cellulose liquor; (3) colloidal silver is obtained by the heat treatment of silver oxide with waste sulphite cellulose liquor; (4) colloidal sulphide of arsenic results from the introduction of sulphuretted hydrogen into a hot solution of arsenious acid in cellulose waste liquor.
