Abstract
A process for the purification of the phosphorous acid from the process of halogenation contrihalogenuro of phosphorus, the halogen acid being expelled by the insufflation of gas at high temperature, characterized in that the crude phosphorous acid is mixed in such a way with 15 to 35 volumetric parts of water and of mother liquor, which is maintained at a temperature of 60 to 75ยบ c, after which gas is blown at this temperature through the mixture, they are allowed to precipitate and the organic impurities are separated, and then they are eventually incorporated into the mixture, at this temperature, more mother liquor is allowed to cool slowly, the crystallized phosphorous acid is separated and the mother liquor thus obtained is returned in a cycle to the process.
