Abstract

17,036. Kapff, S. von, and Nitritfabrik Akt.-Ges. July 21. Formates.-Cellulose formate is produced by treating cellulose in various forms with either concentrated sulphuric acid or a mixture of zinc chloride and formic acid, reprecipitating the cellulose, and, after washing &c., dissolving it in concentrated formic acid; mixtures of, for example, mono-, di-, and tri-formates result. In a modification the formate may be produced by direct treatment with a mixture of zinc chloride and concentrated formic acid.
