OTHER USED
♦ In the photographic industry to protect developer solutions from oxidation. ♦ It is used in the production of rubber chemicals and other chemical compounds. ♦ It is use in other applications include ore flotation, oil recovery, food preservative, making dyes, and detergent.Firstly,sodium sulfide is an important reducing agent. In the field of organic synthesis, Sodium Sulphide 60% Yellow Flakes is often used to reduce organic compounds to their corresponding alcohols. It can participate in reactions, reduce oxygen-containing functional groups to the corresponding hydroxyl groups, and catalyze a series of chemical reactions. In addition, Na2s （1849） can also be used to reduce metal ions, such as reducing manganese dioxide to manganese oxide. Secondly, Sodium Sulfhydrate is an important decolorizing agent. It can remove color from many organic compounds and certain metal ions. sodium polysulfide,HS CODES:283010 is widely used as a depilatory agent in the tanning industry, which can effectively remove hair and cuticles from animal leather. Additionally, sodium sulfide 1313-82-2 60% can remove color from dyes, paints, and other organic materials, leaving them clear and transparent.SPECIFICATION
