Thiourea dioxide, also called formamidine sulfinic acid

The molecular formula two.

CH4N2SO2

Molecular weight:108.12

Melting point:126 C

PH:4

Appearance and properties

Thiourea dioxide is a no oxidation or reduction of stable compounds, for the appearance of white or light yellow crystalline particles, no irritating smell, and solubility in water of 26.7 g / dl (20 degrees C ), saturated water solution pH value of 5. Even in the2030DEG water solution is stable, but in the heating or alkali role, will decompose, free from the strong reducibility sulfinic acid, thus can control reduction.

Thiourea dioxide with higher reduction potential, obvious effect, and the reduction potential of the drop speed is slow, only insurance powder reduction potential reduces the number 1 /5; in addition, but also has good thermal stability, convenient storage and transportation, non-toxic and tasteless, easy operation, convenient storage and transportation etc.. Thiourea dioxide is insurance powder is a new, environmentally friendly alternatives.

Thiourea dioxide with good safety performance, production and use of environmental pollution.
