Chemical Analysis of Glycerin

Abstract

Glycerin is a co-product of heavy fats (hydrolysis), soap making, and transesterification of fats and oils. The history of glycerin and its financial value as an industrial chemical provides an introduction to its importance in our cultures in recent times. Two different types of glycerol are processed, the soapy lye, which contains essential levels of sodium chloride, and the sweet water crude, which has a low concentration of sodium chloride present. Processing glycerol into high purity marks requires pre- treatment measures followed by a loss to consider the glycerol solution into unrefined glycerin.

Removal of sodium chloride requires certain equipment. To process crude glycerin into USP-grade finished glycerin requires a grinding tool, which works under a high vacuum. The final stage of the process is carbon adsorption to remove any colored particles of high molecular weight. Storage of finished and natural glycerin requires special demonstration. The effect of processing the smell and color of glycerin is detrimental to the final quality of the product. Processed plants require special consideration in terms of structure, building materials, materials, controls, and height. Total attention to glycerin processing includes material properties, quality and testing, marks and methods of testing, loss, and waste management. A discussion on glycerin use and future ideas provides a reference to the current glycerin industry. Glycerin is an important product in the production of biodiesel by transesterification, industrial soap by saponification, and, hydrolysis reaction. Attention to glycerol obtained is low due to the presence of bubbles such as prominent catalysts, water, soap, salt, and esters formed during the reaction. The purification of glycerol and the conversion of glycerol into essential products have won growing interest in recent years due to the remarkable progress of the biodiesel industry.
