method for sulfosalicylate hydrazine, its preparation and application as a stabilizer in stannous compounds have antioxidant effect.

摘要

sulfosalicylate hydrazine in response to: [nh2nh2] [c6h3 (cooh) (so3h) (oh)] (b) where a = 1 and b (2), and a process for its preparationin the reaction of sulfosalicylic acid and / or its hydrate with hydrazine and / or its hydrate.according to a molar ratio of 1: 1 to 3: 1 in an aqueous medium at a temperature of between 5 and 60 degrees c.the sulfosalicylate hydrazine can be used for the stabilization of tin compounds with antioxidant activity.especially for electrolytic colouring of aluminium or aluminium alloys.
