Calcium stearate Usage And Synthesis
Overview Calcium stearate also known as calcium octadecanoic acid. Light white crystalline powder. Chemical formula (C17H35COO) 2Ca. The molecular weight is 607.00. Melting point 179~180 ℃, decomposed by heat. Insoluble in water, cold ethanol and diethyl ether, soluble in hot benzene, toluene, and turpentine, slightly soluble in hot ethanol and diethyl ether. It reacts with strong acid to be decomposed into stearic acid and corresponding calcium salt. Water absorption in the air. Intolerance lipolytic microorganisms. Pyrolysis to generate stearin ketones and hydrocarbons. Non-toxic. Industrial often mixed with the corresponding oleate.As stabilizers and lubricants of polyvinyl chloride; as halogen absorbent of polyethylene and polypropylene; as lubricants of polyolefin fibers and molded products; as lubricant and release agent of phenolic, amino and other thermosetting plastics; as intensifier of lubricating grease; as waterproofing agent of waterproof fabric; etc. Food grade Calcium stearate serves as an anti-caking agent. Dilute soap is made by the reaction of melt stearic acid and sodium hydroxide, reacting with calcium chloride, and Calcium stearate is obtained . 
It can be used as heat stabilizer of polyvinyl chloride, it has excellent lubricity. Thermal stability performance is general, and is less than barium stearate, lead stearate, tin stearate and cadmium stearate. But it is cheap, low toxicity, good processability. Combined with Zinc soap and an epoxy compound, it shows a synergistic effect, improving the thermal stability, and it is commonly used for requirements nontoxic soft products, such as food packaging films, medical instruments, etc. It combines with the base lead salts and lead soaps used for hard products, increasing the gelation speed. Calcium stearate is used for polyethylene and polypropylene, and it can eliminate the adverse effects of residual catalyst on the resin color and stability. This product is also widely used as lubricant and release agent of thermosetting plastics, such as polyolefin, polyester reinforced plastics, phenolic resin, amino resin, etc.
The disadvantage of Calcium stearate is initial color. When heating at above 100 ℃ with longer time, Calcium stearate will make the white PVC become a reddish color. Particularly when titanium dioxide exists in formula, coloring is particularly serious. At this point, if 0.06~0.12% Na2CO3 or 0.09~0.19 NaHCO3 are added, it can overcome this shortcoming. But because these substances are too alkaline, they are not used in practice. In addition, when the amount of this product is large, there is segregation scaling phenomenon.
Barium stearate Barium stearate, also known as " barium octadecanoic acid ", chemical formula Ba (C18H35O2) 2. The molecular weight is 704.13. White fine powder. Melting point 160 ℃, relative density of 1.15. Insoluble in water, soluble in cold ethanol, soluble in hot ethanol, benzene, toluene, and other non-polar solvents, after heated and dissolved in an organic solvent , and cooled into jelly. Encountered strong acid, Barium stearate can be decomposed into stearic acid and corresponding barium salt. Water absorption in the air.Preparation method: Stearic acid reacts with barium carbonate or barium hydroxide, or sodium stearate solution reacts with dilute barium chloride solution, Barium stearate is obtained . Barium stearate can be used as waterproof products, alkali pump packing, and can also be used as high-temperature lubricants and fillers of machine; heat resistance and light fastness of stabilizers of polyvinyl chloride plastics, high temperature resistant powder mold of rubber products. Barium stearate is toxic, toxicity coefficient T = 2, the typical symptoms of poisoning are vomiting, abdominal pain, diarrhea, increased blood pressure, pulse rate disorders, etc.
Anti-caking agent Anti-caking agent, also known as caking inhibitor, is used to prevent the particles and powdered food from aggregation and agglomeration, maintaining its loose or free flowing substances. Its particles is tiny, loose porous and strong adsorption. It easily absorbs the water and oil which lead to the formation of agglomerates, making food to maintain a powder or granules state.
There are five species of anti-caking agent which are permitted to be used in China: potassium ferrocyanide, sodium aluminosilicate, tricalcium phosphate, silica and microcrystalline cellulose.
Anti-caking agents are varied, in addition to five kinds which are permitted in China, aluminum, silica, calcium silicate, Calcium stearate, magnesium carbonate, magnesium stearate, magnesium, magnesium phosphate, magnesium silicate, kaolin, talc and ferrocyanide are permitted to be used in Foreign. In addition, they have anti-caking effect, and some also have other effects, for example, calcium silicate and kaolin also has the function of filter aids, and Calcium stearate and magnesium stearate have emulsifying effect. And in addition that ferrocyanide has limited ADI value, security of other varieties are very good, ADI values are no provisions. Based on requirement, proper developments are still needed.
