Stearic Acid Chemical Structure
Stearic acid is a common fatty acid. Its chemical structure is CH < unk > (CH < unk >) < unk > COOH. In this structure, it contains a straight-chain alkyl group composed of eighteen carbon atoms, one end is methyl (CH < unk >), and the other end is carboxyl (COOH). The chemical structure of stearic acid has significant influence in many fields. In oil chemistry, it often exists in animal and vegetable oils and can be obtained by hydrolysis and other reactions. Due to its unique chemical structure, stearic acid is hydrophobic and insoluble in water, but soluble in organic solvents. In industry, it is often used in the manufacture of lubricants, emulsifiers, cosmetics, etc. because of its chemical structure properties. Taking lubricants as an example, with their long-chain alkyl structure, friction between surfaces can be reduced; in cosmetics, this structure can improve product texture and enhance stability. In short, the chemical structure of stearic acid determines its many physical and chemical properties and plays an important role in many industries.
