Abstract

15,445. Carlson, O. F. Feb. 28, [date applied for under Patents Act, 1901]. Cyanides ; cyanamides. - Carbide-nitrogen compounds are prepared from carbides of alkaline earths at a lower temperature than heretofore by adding fluorspar, or one or more alkaline-earth fluorides, with or without a sulphate of an alkaline earth or alkali. The addition of from 5 to 30 parts of fluorspar to 100 parts of calcium carbide, with or without the addition of an alkali or alkaline-earth sulphate, has been found effective. The difficulty of procuring suitable vessels for the carbide is diminished by this method. The carbide-nitrogen product is stated. to be more suitable for use as a fertilizer than that heretofore produced by calcium chloride, since it is not hydroscopic.
