Thiourea Dioxide

 As an odorless white powder and one stable compound without oxdability and reducibility, its solubility in water is 26.7g/l(20℃), the PH value of saturated aqueous solution is 5. It shows extremely stability even in 20-30℃aqueous solution, but will resolve and dissociate sulfinic acids once heated or in presence of alkali.
Uses:As a new environmental-peotection reductant,which can be used as substitute hydrosulfite,Thiourea dioxide is more heat stable,with high reducibility,easy operation.It also can be used in textile processing,bleaching and reductiveclear, photographic industry as a component of stripping agent.It widely applies to reduction dyes and sulfur dyes dyeing,wool and silk bleaching,disperse dyes clean,dye vat cleaning and so on.
