Abstract
Tar acids are purified by treatment in the liquid phase with a metal which will cause the evolution of hydrogen on contact with an aqueous mixture containing tar acids, alkaline solutions or mineral acid solutions such as aluminium, zinc, iron, nickel, tin, magnesium or calcium. The tar acids may also be treated with gelatinous metal hydroxides such as iron hydroxide before or after treatment with the metal. In examples an alkaline solution of tar acids or a mixture of tar acids and sulphuric acid are treated with zinc dust. The Specification as open to inspection under Sect. 91 refers to the purification of tar acids by the use of gelatinous metal hydroxides alone. This subject-matter does not appear in the Specification as accepted.
