Stearic Acid Professional Production

Stearic acid is a kind of fatty acid, chemical formula C18H36O2, commonly used as a raw material for cosmetics, detergents, plastic auxiliaries and so on. The production of stearic acid is usually carried out through the following steps: Raw material preparation: The main raw material of stearic acid is vegetable oil or animal fat, such as palm oil, coconut oil, etc. These raw materials are refined and purified to remove impurities and impure substances. Hydrogenation reaction: The unsaturated fatty acids in the raw material are hydrogenated to convert them into saturated fatty acids. This step is usually performed under high temperature and pressure, using a catalyst such as nickel or palladium. Crystallization separation: the hydrogenated mixed fatty acid solution is cooled and crystallized to precipitate stearic acid from the solution. The stearic acid is separated by filtration or centrifugation. Refining treatment: The separated stearic acid is refined to remove impurities and impure substances. This step usually involves distillation, crystallization, washing and other processes. Packaging and storage: The refined stearic acid is packaged into appropriate containers and stored. Stearic acid should be stored in a dry, cool, ventilated place, away from direct sunlight and humidity. The above is the general production process of stearic acid, the specific production method and process may vary depending on the manufacturer and product requirements.
