Technical Document

Brief Overview

Stearic acid, frequently referred to as octadecanoic acid, is a popular and beneficial type of saturated fatty acid that may be found in both animal and plant-based fats. It is a waxy white solid with the chemical formula of CH3(CH2)16CO2H and molar mass of 284.48 g/mol. . In their natural form, oleic, palmitic, and stearic acids make up these fats; about equal amounts of oleic and palmitic acids are used to make a commercial stearic acid. Stearic acid is commonly found in mixed triglycerides with other long-chain acids or as an ester of fatty alcohol in nature. It's stated that animal fats often have higher stearic acid content than vegetarian fats.

Manufacturing Process

Fatty acids serve a purpose in the manufacture of stearic acid; the method used in this process is determined by the quality of the final product and the raw material used. Different protocols are used in accordance with these standards. The most widely used raw materials for the synthesis of stearic acid are tallow and grease. There are two main steps in the production process:

a. Hydrolysis : To produce glycerin and fatty acids, the raw ingredients (oil or fat) first go through hydrolysis. The next action is to separate the two final products.

b. Separation : The purification and separation of the fatty acid mixture are included in the second stage.

Paint Industry
