Octadecanoic acid, another name for stearic acid, is a saturated fatty acid that is found in high fat plant and animal sources. It is widely known to have several health benefits. It is a waxy white solid with a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H. These fats naturally contain oleic, palmitic, and stearic acids; nearly equal amounts of oleic and palmitic acids are necessary for the synthesis of commercial stearic acid. Commonly, stearic acid can be found in nature as a mixed triglyceride containing other long-chain acids or as an ester of fatty alcohol. Notably, compared to fats derived from plants, animal fats frequently have a higher stearic acid content.
Manufacturing Process
Fatty acids play a crucial role in the synthesis of stearic acid, with the manufacturing process customized to meet specific quality standards and chosen raw materials. Various procedures are employed to adhere to these criteria. Tallow and grease are the primary raw materials prominently used for stearic acid synthesis. The production process consists of two main stages:
a. Hydrolysis: Raw materials (oil or fat) undergo hydrolysis, leading to the creation of glycerin and fatty acids. Subsequently, the two end products are separated.
b. Separation: In the second stage, the purification and separation of the fatty acid mixture refine the stearic acid production process.
