Technical Document

Brief Overview

One common and advantageous kind of saturated fatty acid found in both animal and vegetable fats is stearic acid, also known as octadecanoic acid. It is a waxy white solid with the chemical formula of CH3(CH2)16CO2H and molar mass of 284.48 g/mol. These fats are made up of oleic, palmitic, and stearic acids in their natural state; industrial stearic acid is made from almost equal parts oleic and palmitic acids. Stearic acid occurs naturally as an ester of fatty alcohol or in mixed triglycerides with other long-chain acids. It's important to remember that, on general, animal fats contain more stearic acid than vegetarian fats.

Manufacturing Process

Stearic acid is manufactured using fatty acids, with the manufacturing process being contingent upon the chosen raw material and the desired stearic acid quality. Various procedures are employed based on these criteria. Tallow and grease are the most commonly utilized raw materials for synthesizing stearic acid. The production process involves two primary steps:

a. Initially, the raw materials (oil or fat) undergo hydrolysis to generate glycerin and fatty acids. The subsequent step involves separating the two resulting products.

b. The second stage encompasses the purification and separation of the fatty acid mixture.
