Mainly by the grease hydrolysis method for industrial production.
Stearic acid with gc-ms forms exist in animal fat imitation, oil and some vegetable oil, the oil via hydrolysis drawees stearic acid.
Stearic acid is a widespread nature fatty acids, almost all are in the oil content of the stearic acid, ranging in animal fats, such as butter higher in the content in can amount to 24%, vegetable oil, tea oil content in less for 0.8%, palm oil for 6%, but the content is as high as cacao fat 34%.
Industrial stearic acid production methods are mainly fractionation method and squeezing method two kinds. In sclerotic oil, then add decomposition agents have thick fatty acid hydrolysis, then after washing, distillation, decoloring drawees finished products. Meanwhile byproduct glycerol.
