Abstract

Stability: It is stable in acidic solution, easy to decompose under alkaline conditions

Stability: It is stable in acidic solution, easy to decompose under alkaline conditions, and generates sulfonic acid with strong reducibility, which makes this product have controllable reduction effect. When the alkaline solution dissolved with urea sulfur dioxide is heated, it has a high reduction potential (-1230Mv), which will decompose and free the reductive sulfonic acid, so it reflects a strong reduction activity.
Reaction characteristics: obtained by the reaction of thiourea with hydrogen peroxide.
