Manufacture Thiourea Dioxide/TDO/TUD

Thiourea Dioxide, TDO, TUD 1758-73-2, used as reducing agent White crystal powder, high reducibility,excellent heat stability

Shouguang Xinsheng Chemistry Co., Ltd is a professional manufacturer and exporter of Thiourea Dioxide, pulp bleaching agent FAS.

 

Thiourea Dioxide (TDO or TUD) is also named as Formamidine Sulfinic Acid. Its

appearance is white crystal powder. Thiourea Dioxide is a stable compound with no strong

reducing and oxidizing ability, and its dissolvability is 26.7g/l (20 degrees centigrade),while its PH is 5.0 insaturated solution. TDO appears terrific stable even in 20 -30  degrees centigradesolution, but when it is under heat or catalysesing by alkali, it decomposes gradually to produce sulfoxylic acid

through formamidine sulfinic acid to exhibit a reducing action.

TDO is a new kind of reducing agent that used as exchange of sodium hydrosulfite. It is

widely used in textile and paper making industry. This product is also used in leather

processing industry, paper, pulp and board industry, photographic industry, bleaching and

reducing agents. This product is also a component of decolorisation agents. In

macromolecule material industry, it is used as catalysis agent and stabilizer of resinic

producing, and it is also used in organic synthesization of sensitizing material, and

medicine, medical, spicery materials in fine chemicals, and also can be applied in the

recycling and separating of heavy metals.
