Abstract

8818. Wade, H., [Deutsch-Koloniale Gerb.- und Farbstoff-Ges.]. April 7. Tanning with special chemicals.-Condensation products from formaldehyde and naphthol monosulphonic acids or heteronuclear naphthylamine monosulphonic acids are used in tanning. A tanning-liquor may be made by dissolving the condensation product in water and adding alkali to nearly neutralize the solution, or the reaction mixture can be diluted and used directly.
