Abstract

27,900. Wolff, A. Dec. 12. Chrome tanning.-Chrome leather is made by treating cleaned, pickled, and unhaired skins with an aqueous solution of chromium formate. The chromium formate may be made by mixing solution of chromium sulphate and sodium formate and separating the precipitated sodium sulphate, or by stirring solid sodium formate into a concentrated solution of chromium sulphate; either a neutral or basic solution of chromium sulphate may be employed. During the tannage, only formic acid is liberated. Specification 14,293/96 is referred to.
