Hypophosphorous Acid

Hypophosphorous acid 50% - H3PO2 (CAS: 6303-21-5) Hypophosphorous acid 50% an ionic compound that can be synthesized by reacting boric acid Intermediates hydrofluoric acid Intermediates then adding additive hydroxide. The most general method to prepare hypophosphorous acid is by hydrolysis of dialkyl phosphonate to phosphonic acid with concentrated HCl solution. Hypophosphorous acid is used as a bleaching or decolorizing agent for plastics, synthetic fibres, and chemicals and also as a colour stabilizer and decolourizing agent in the manufacture of several plastics and chemicals. In electroplating it is used as a wetting, emulsifying or dispersing agent. The substance is used as an acidifying compound, chemical reducer, anti-oxidant, catalyst, in synthesis and electroless nickel plating and as a polishing agent.

Bilirubin is extracted from bile of animals. It is very effective on relieving convulsion , allaying a fever , detoxifcation , decreasing blood pressure and promoting number of eosinophils in the blood . It is the basis of calculus bovis ariifactus and it also be used to make cosmetics , medicine , health products etc . Our bilirubin has past thin layer chromatography and liquid chromatography test by hubei entry & exit inspection and quarantine bureau technology centre . We can produce 40~50kg bilirubin every month , its purity is 95% -99%, and the structural stability is well, the purity doesn't reduce in more than one year .
