Abstract
Cation-exchange materials, which can be used for adsorbing bases from smoke, vapours or gases, for example for removing nicotine from smoke, are obtained by treating carbonaceous organic materials of mineral or vegetable origin with nascent oxygen in a concentrated acid, or alkaline medium, the oxidation potential being at least 1,1 volt. The nascent oxygen may be set free in the acid or alkaline medium by dissolving therein a strong oxidizing agent. An oxidation catalyst may be present. Or the nascent oxygen may be liberated electrolytically. The materials may be subjected to two or more such treatments successively. In examples described lignite, coal or anthracite is treated with acid or alkali containing potassium chlorate or alkali bichromate.ALSO:Cation-exchange materials, which can be used in purifying sugar juice or in the preparation of pharmaceutical products, are obtained by treating carboniferous organic materials of mineral or vegetable origin with nascent oxygen in a concentrated acid or alkaline medium, the oxidation potential being at least 1,1 volt. The nascent oxygen may be set free in the acid or alkaline medium by dissolving therein a strong oxidizing agent. An oxidation catalyst may be present. Or the nascent oxygen may be liberated electrolytically. The materials may be subjected to two or more such treatments successively. In examples described lignite, coal or anthracite is treated with acid or alkali containing potassium chlorate or alkali-bichromate. Pharmaceutical products can be prepared by combining these base-exchange materials with alkaloids or other organic bases. In an example a solution of the chlorhydrate of butylester of p-dibutyl-amino-benzoic acid is run over base-exchange material saturated with calcium ions; it is stated that the product, when applied to a wound, stops h morrhage and sterilizes the wound. Specification 492,316, [Group I], is referred to.ALSO:Cation-exchange materials are obtained by treating carboniferous organic materials of mineral or vegetable origin with nascent oxygen in a concentrated acid or alkaline medium, the oxidation potential being at least 1,1 volt.

In examples described, lignite, coal or anthracite is treated with acid or alkali containing potassium chlorate or alkalibichromate. The products obtained can be used in treating water, the manufacture and separation of salts by base-exchange processes, the purification of sugar juice, for adsorbing bases from smoke, vapours or gases, for example for removing nicotine from smoke. Pharmaceutical products can be prepared by combining these base-exchange materials with alkaloids or other organic bases. In an example, a solution of the chlorhydrate of butylester of p-dibutylaminobenzoic acid is run over base-exchange material saturated with Ca cations; it is stated that the product, when applied to a wound, stops h morrhage and sterilizes the wound. Specification 492,316 is referred to.
