Introduction fatty acid metal salt production process

 Fatty acid salt is closely related with people's lives, and its many types, such as fatty acid  Stearate zinc sodium salt (soap) is commonly used in detergents, fatty acids and divalent and trivalent metal salts generated by the use of products in the industry is very extensive. This paper describes the use of fatty acid alkaline earth metal salts, preparation principles and production technology for the utilization and development of oil companies oil fine chemical products reference. 1 fatty acid salt thereof, in addition to ammonium salts of fatty acids, potassium, sodium, almost all of the  epoxidized soybean oil carbon chain fatty acid metal salts are not soluble in water, very low solubility in polar solvents, in a non-polar solvent presented in the gel, only the mineral oil and grease can be dissolved. All fatty acid salts have different crystal forms. Melting point fatty acid salt is one of the important indicators of things, its melting point in the range of 1 8 ~ 2 66 ℃, with the fatty acid carbon chain length, degree of saturation and different types of salt and a larger difference. According to statistics, various fatty acid salts of calcium in the largest amount, about 60%, followed by zinc, accounting for about 20%, other about 20 percent of magnesium, lead salts, cadmium salts. The main purpose of fatty acid salts are: 1.1 for the polymer industry, such as carbon chain saturated fatty acid salts of caprylate in  antimony trioxide polymers is often used as a heat stabilizer, a curing agent and catalyst; carbon chain saturated fatty acid salts hydrocarbons such as stearic acid salts can be used as the polymer material mold release agents, stabilizers and lubricants, a variety of polyester desired fat ......
