Dl-tartaric Acid Raw Materials powder Dl-tartaric Acid Details
Dl-tartaric Acid powder Usage and Synthesis.
DL-Tartaric acid is widely used in food, medicine, chemical industry, light industry, etc. It is mainly used in the manufacture of tartaric acid salts, such as potassium antimony tartrate, sodium potassium tartrate, etc. Its salts are used as mirror silver plating and metal treatment.
In the food industry, it is used as beer foaming agent, food souring agent and flavour correcting agent. Its acidity is 1.3 times that of citric acid, and it is especially suitable for the souring agent of grape juice. In the textile industry, tartaric acid is used as a mordant to control the release of chlorine from bleaching powder. It is used in medicine for the manufacture of Simcorphone. The product has been identified as an excellent food additive by the FAO/WHO Expert Committee. It also plays a very important role in tanning, photographic, glass, enamel and telecommunication equipment industries.
Uses of Dl-tartaric Acid powder.
DL-Tartaric acid can be used as acidulant, chelating agent, antioxidant synergist, aroma enhancer, quick-acting bulking agent acidic substance, food colour dilution, curing agent.DL-Tartaric acid is widely used in food, medicine, chemical industry, light industry and so on, mainly used in the manufacture of tartaric acid salts, in the food industry used as a beer foamer, food acidulant, flavour correcting agent, acidulant of grape juice. It is also used in leather tanning, photography, glass, enamel, telecommunication equipment and so on.
Preparation of Dl-tartaric Acid powder.
Product Method of Bulk Dl-tartaric Acid powder.
1.maleic anhydride oxidation method maleic anhydride and hydrogen peroxide solution under the action of tungstic acid for the reaction, the generation of epoxysuccinic acid, and then by hydrolysis, get tartaric acid, and then cooling, crystallisation, separation and drying to get the pure product.
2. Tartar method takes crude tartar from wine making as raw material, which is processed into calcium tartrate by lime emulsion and then acidified by sulfuric acid.
