Abstract
1448208 Stabilized dithionite compositions BOC Ltd 10 Sept 1973 [8 Sept 1972] 41846/72 Heading C1A [Also in Division D1] A stabilized substantially anhydrous dithionite composition comprises a major proportion of a metal dithionite and as a stabilizer a carboxylic acid salt of a primary, secondary or tertiary amine, which amine having at least one hydrocarbon group of at least five carbon atoms. It is preferred to use the method for the stabilization of No, K, Ca and Zn dithionites and examples are given of the stabilization of Na dithionite using tallow amine acetate, coconut amine acetate, stearyl amine acetate, oleylamine acetate, secondary oleylamine acetate and secondary tallow amine acetate in 2% by wt. concentration. Addition of the stabilizer can be carried out by mixing of the solids, or solid dithionite and molten stabilizer, or by the use of a mutual solvent with subsequent removal. A novel test procedure for the evaluation of the effectiveness of stabilizers is described.
