Abstract
306,046. Jost, F. Feb. 14, 1928, [Conven. tion date]. Manures.-Alkali chlorides, for instance sodium chloride, are treated with phosphoric acid to obtain alkali phosphates and the latter treated with calcium nitrate to produce alkali nitrates and calcium phosphate, which are separately recovered. lf excess of calcium nitrate is used a mixture of alkali and calcium nitrates for use as a fertilizer may be obtained. The c calcium phosphate may be treated with sulphuric acid to obtain the phosphoric acid used in the process and the calcium sulphate also formed be converted first to calcium carbonate with ammonia and carbon dioxide and then to nitrate, for use in the process, with nitric acid with recovery of carbon dioxide ; alternatively the calcium phosphate may be treated with nitric acid, and the mixed solution of phosphoric acid and calcium nitrate obtained be used to obtain alkali nitrate from the chloride in a single treatment. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-a fertilizer consisting of a mixture of alkali and calcium nitrates with alkali phosphate. This subject-matter does not appear in the Specification as accepted.
