Detailed Photos
Stearic acid is one of the main long-chain fatty acids that make up oils and fats. It exists in animal fats, oils and some
vegetable oils in the form of glycerides. Stearic acid is obtained by hydrolysis of these oils. Stearic acid is a kind of fatty
acid widely existing in nature. It has the chemical properties of general carboxylic acid. Almost all oils contain stearic acid
with different content. The content of stearic acid in animal fat is higher, such as 24% in butter, less in vegetable oil, 0.8% in tea oil and 6% in palm oil, but the content in cocoa butter is higher. Up to 34%. The main production methods of industrial stearic acid are fractionation and pressing. The crude fatty acid is hydrolyzed by adding decomposing agent in hardening oil, and then the product is washed, distilled and decolorized. The by-product is glycerol.
