Widely recognized and beneficial, stearic acid, also known as octadecanoic acid, is a saturated fatty acid present in fats from both plant and animal sources with high fat content. With a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H, it manifests as a waxy white solid. In its natural state, these fats contain oleic, palmitic, and stearic acids, and roughly equal parts of oleic and palmitic acids are essential for commercial stearic acid production. Stearic acid is commonly found in nature either as an ester of fatty alcohol or in mixed triglycerides with other long-chain acids. Notably, the concentration of stearic acid in animal fats is often higher than in plant-based fats.
Manufacturing Process
Fatty acids play a pivotal role in the production of stearic acid, with the manufacturing approach tailored to meet specific quality standards and the chosen raw materials. Various procedures are applied to align with these criteria. Tallow and grease stand out as the primary raw materials for synthesizing stearic acid. The production process involves two key stages:
1. Hydrolysis: Raw materials (oil or fat) undergo hydrolysis, resulting in the generation of glycerin and fatty acids. Following this, the two final products are separated.
2. Separation: The second stage encompasses the purification and separation of the fatty acid mixture, refining the stearic acid production process.
