Green Powder Chrome Tanning Agent Basic Chrome Sulphate

Basic inorganic chemistry, Chemistry Inorganic. The original refers to compounds that are related to or derived from non-living things, and generally refer to compounds that do not contain carbon atoms except carbonates and carbon oxides. Such as Fundamental Inorganic Chemistry, Inorganic Compounds, inorganic acids, inorganic salts, inorganic coatings, inorganic pigments, inorganic fertilizers and so on;

Inorganic salt is the substance composed of metal or ammonium ions and acids. The Inorganic Salts List includes bulk and niche products such as sodium silicate, aluminum sulfate, sodium sulfate, borax, boric acid, yellow phosphorus, phosphoric acid, sodium triphosphate, carbon disulfide, calcium carbonate, etc., which are the most important Inorganic Salts Examples in the inorganic salt industry. Some Type Of Salt , although the yield is small, are very important, such as the annual output of iodine in the world is only about 10 kt, but the use of products has a high added value and is necessary for many chemical reactions.

The production process of basic chromium sulfate mainly include organic matter reduction method and sulfur dioxide reduction method.  Organics reduction method: the sodium dichromate mother liquor with sodium bisulfate solution or sulfuric acid in the lead lining or glass-lined belt stirring reactor stirred after stirring acidification, under the stirring slowly add sucrose reducing agent, so that hexavalent chromium reduction, the end of the reaction to keep the solution boiling, is conducive to the complete reaction. The reaction product is a syrup-like viscous liquid, add water to adjust the solution concentration to 40 ~ 42086, first through natural cooling, and then frozen in the cooling crystallizer to 10 ° C or less, so that part of the sodium sulfate to generate glauber salt crystals, separated by centrifugation, the liquid basic chromium sulfate products are prepared, and then concentrated and dried to obtain solid basic chromium sulfate finished products.

 We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide , Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:
