Abstract

294,236. American Potash & Chemical Corporation, (Assignees of Burke, W. E., and Ropp, H. de). July 22, 1927, [Convention date]. Drawings to Specification. Boric acid.-In a cyclic process for preparing boric acid, borax, which may be partly or wholly dehydrated, is treated with sulphuric acid, and boric acid separated by crystallization. Borax and water are added to the mother liquid which is cooled to separate sodium sulphate. The residual liquor is mixed with sulphuric acid and borax and again treated for the separation of boric acid The solution to which borax and sulphuric acid are added may be heated and concentrated by evaporation, and may be subsequently cooled to effect crystallization by evaporation under reduced pressure.
