Abstract

81. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Jan. 1. Formaldehyde hyposulphites. - Easily soluble zinc formaldehyde hyposulphite (hydrosulphite) is formed by causing formaldehyde, zinc dust, and sulphur dioxide to interact in the presence of water, while so moderating the reaction as to prevent or partially prevent the formation of the difficultly soluble basic zinc formaldehyde-sulphoxylate described in Specification No. 7592, A.D. 1905. The temperature should preferably be about 20‹ C. and must not exceed 50‹ C. The sodium salt is obtained from the thick syrup of the zinc salt by treatment with sodium carbonate. By boiling the zinc salt with zinc dust, basic zinc formaldehyde sulphoxylate is obtained.
