Abstract

1342344 Phosphoric acid W & H M GOULDING Ltd 11 Jan 1971 [30 Jan 1970] 4561/70 Heading C1A Crude phosphoric acid is upgraded by adding a completely water soluble organic liquid to precipitate impurities, filtering, and treating the filtrate to recover organic liquid. The H 3 PO 4 may be concentrated prior to upgrading, and a water soluble inroganic salt may be added Preferred organic liquids are alcohols, ketones, and ethers. [GB1342344A]
