| Colour: White, odorless crystalline powder pH value 4 (10g/l, H2O, 20ºC) Physical properties: White odorless crystal powder, it is a stable compound with neither oxidizing nor reducing properties. The solubility in 1L of water is 26.7g. Acidity coefficient (pka) : 2.40 + / - 0.10 (Predicted) Solubility It is slightly soluble in water, and its aqueous solution is acidic. It is insoluble in ether and benzene. It decomposes into urea and hyposulfuric acid in a slightly alkaline solution. Stability Sensitive to water, avoid contact with air, water and oxides The toxic effect of this product is similar to that of thiourea, but stronger. Storage temperature: 2-8°C |
| It is used as an additive for synthetic fibers, a decolorizing agent, an emulsifier for photographic films, a polymerizing agent for chloroprene, and a separator for rhodium and iridium, etc |
| Urea sulfur dioxide, as a reducing agent, is widely used in the printing and dyeing industry for wool bleaching, dyeing of VAT dyes and sulfur dyes, as a reducing cleaning agent for disperse dye dyeing, and as a discharge and decolorizing agent. It is used in organic synthesis to reduce ketones, quinones, nitro groups, azo groups, azo oxides, azo oxides, subazo compounds and organic sulfides, etc. Urea sulfur dioxide is also used as a various decolorizing agent, a sensitizer for photographic gelation latex, a chemical reagent for separating rare metals rhodium and iridium, and can improve the stability of polyethylene. Adding urea sulfur dioxide during the evaporation process of polyacrylonitrile and polymerization can improve the color of polyacrylonitrile and is an important supporting product for the production of synthetic fibers. This product is also widely used in the production of fine chemical products such as spices, etc. |
| Reagents for reducing ketones to secondary alcohols. Separate the rare metals rhodium and iridium. Photographic latex sensitizer. Polyvinyl chloride stabilizer |
| A simple reagent for reducing ketones to secondary alcohols |
| Widely used in the chemical and textile industries, it is a strong reducing agent and is increasingly replacing sodium hyposulfite to occupy a significant position in the dyeing and printing field |
