Popular and advantageous, stearic acid (also known as octadecanoic acid) is a saturated fatty acid that can be found in fats derived from plants and animals that are also high in fat content. With a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H, it is a waxy white solid. These fats are composed of the acids oleic, palmitic, and stearic in their natural state; roughly equal parts of oleic and palmitic acids are required to create commercial stearic acid. Stearic acid is frequently found in nature as an ester of fatty alcohol or in mixed triglycerides with other long-chain acids. It is said that the concentration of stearic acid in animal fats is frequently higher than in vegetarian fats.
Manufacturing Process
Fatty acids play a crucial role in the manufacturing of stearic acid, and the approach employed in this process is contingent on both the quality specifications for the final product and the chosen raw material. Different procedures are implemented in alignment with these criteria. Tallow and grease are the predominant raw materials utilized for the synthesis of stearic acid. The production process comprises two primary steps:
a. Hydrolysis: Raw ingredients (oil or fat) undergo hydrolysis to generate glycerin and fatty acids. Subsequently, the two final products are separated.
b. Separation: The second stage involves the purification and separation of the fatty acid mixture.
