1. Description of the product
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 5.0in saturated solution. TDO appears terrific stable even in 20-30 degrees centigrade solution, but when it is under heat or catalysesing by alkali, it decomposes gradually to produces sulfoxylic acid through formamidine sulfinic acid to exhibit a reducing action. Thiourea dioxide 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 macromolecule material industry, it is used as catalysis agent and stabilizer of resinic producing, and it is also sued 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 heavey metals.
2. storage points for attention
Store in a cool (below 30degrees centigrade), dry,well ventilated area away from all source of ignition and our of direct sunlight ,keep away from incompatible materials, keep containers tightly closed, do not store in unlabeled or mislabeled containers. Protect from moisture. Do not store near combustible materials. Keep containers well sealed, seal only with original vent cap. Ensure pressure relief and adequate ventilation. Store separately from organics and reducing materials. Avoid contamination which may lead to decomposition
