产品介绍：

有二氧化硫气味。对湿敏感。有酸性反应。与酸接触有二氧化硫逸出。在空气中逐渐氧化成硫酸盐，在湿空气中氧化更快。如研磨成粉灼热时能燃烧。易溶于水，不溶于醇。190℃时分解。有刺激性。 Potassium disulfite (Potassium metabisulfite, PMB) is an inorganic salt with antimicrobial properties. It is a sulfiting agent that prevents browning of foods. Its genotoxic and cytotoxic effect has been assessed. PMB undergoes hydrolysis to form potassium bisulfite.Potassium disulfite has been used in a protocol for the modification of the polydimethylsiloxane (PDMS) polymer surfaces. It may be used in the following processes: 还原剂，显影剂，细菌抑制剂，抗氧剂，制备亚硫酸。 · Chemical etching of poly(vinylidene fluoride) in β-phase (β-PVDF) irradiated films. · Decolorization during the synthesis of 2-iodopyrimidine derivatives. · Palladium-catalyzed aminosulfonylation of aryl halides.
