Effect of Glycine and Monoethanolamine on the Stability and Reductive Activity of Thiourea Dioxide in Aqueous Solutions

Abstract

The effect of glycine and monoethanolamine on the stability and reductive activity of thiourea dioxide in the reaction with acid orange II dye was studied. It was found that, in contrast to glycine, introduction of additives of monoethanolamine into aqueous solution of thiourea dioxide substantially increases its reductive activity in alkaline solutions, although the stability of the thiourea dioxide monoethanol amine derivative in alkaline solutions is much lower than that of thiourea dioxide and the product of its reaction with glycine.
