What is calcium stearate? Calcium stearate, also known as calcium octataectae, belongs to an organic compound with the appearance of a white light crystalline powder. The chemical formula (C17H35COO) is 2 Ca. The molecular weight of 607.00. The melting point ranges from 179 to 180℃, subject to high thermal decomposition. Insoluble in water, cold ethanol Chemicalbook and ether, soluble in hot benzene, toluene, and turpentine, and slightly soluble in hot ethanol and ether. Strong acids decompose into stearic acid and the corresponding calcium salts. There is water absorption in the air. Li-intolerant microorganisms. High-temperature decomposition to generate stearine and hydrocarbons. Non-toxic.
Methods of production For the synthesis of calcium stearate, the calcium chloride solution of 1074 kg/m3 (10°Be) was added to the sodium stearate solution prepared above, and the decomposition reaction was carried out at about 65℃. The product calcium stearate was precipitated by precipitation. Then after filtration, washing, and drying at about 90℃, that is, the finished product. It can also be used: stearic acid is dissolved in 20 times the mass of hot water, add saturated caustic soda solution, and conduct saponification reaction at about 75℃ to produce a dilute sodium stearate solution. The calcium chloride solution with a content of 1074 kg/m3 was added to the sodium stearate solution, and the decomposition reaction was conducted at about 65℃. The product calcium stearate was precipitated by precipitation. Then after filtration, washing, and drying at about 90℃, that is, the finished product.
Main uses of calcium stearate Calcium stearate can be used in the pharmaceutical industry to prepare to cure oil and lubricants and as a paint desiccant. For the processing of PVC and rubber non-toxic products, with calcium stearate, barium stearate, and utensils synergistic effect, can effectively improve the photothermal stability of PVC and rubber products, the amount of PVC processing is usually <1. And can be used in rubber products, touch agents, PP, PE, PS, EPS polymerization additives, and pencil lead manufacturing. In addition, zinc stearate can be used as a heat stabilizer; lubricant, grease; promoter, thickening, etc. For example, it is generally used as a PVC resin thermal stabilizer. Finally, it is used for general industrial transparent products; calcium soap can be used for non-toxic products. Generally, this product is used for soft products, but in recent years has begun to use hard transparent products such as water bottles, water pipes, and other products. This product is good lubricity and can improve the phenomenon of scale precipitation, but it also works as a lubricant, release agent, and paint smooth agent, paint additive.
Price of calcium stearate The different price of calcium stearate purity is also different. The market price of calcium stearate is in the process of dynamic change. The price of calcium stearate can be found on our company's official website. If you need it, you can ask us at any time.
