Glycerin

What it is pure or USP Glycerin?

Glycerin is a very important molecule that is used in different fields and areas. It is also known as glycerol and it is a triol (triol) with a skeleton of 3 carbons, all occupied by a hydroxyl group, hence its name IUPAC: propane-1, 2, 3-triol or 1, 2, 3 propanetriol .

Tab 1

Liquid glycerin is mainly obtained by the hydrolysis of fats and oils using the Fat Splitting method: ie, a splitting of fats / oils Colgate-Emery yielding two products: crude glycerin (to a concentration of approximately 12-15%) and free fatty acid chains.

The traditional method used for fats and oils in the glycerin was achieved by the saponification of fats and oils, as if it was a byproduct of glycerin for soap production. The triglyceride reacts with caustic providing soap and glycerin.

Another method highly developed and booming to get it is by transesterification reaction of oils and fats for biodiesel. Oils and fats react with an alcohol (methanol or ethanol) in order to yield methyl or ethyl esters and glycerin.

However, the latest and most modern mechanism for glycerin is related to the progress of industry of polymers derived from propylene, specifically in the synthesis of epichlorohydrin (precursor of plastic resins, epoxy, exchange, etc.).

Glycerin is a means of great relevance in the oleochemical industry. Plasticity and excellent properties enable a wide range of uses in different markets. The safety of vegetable glycerin, efficiency and performance of oleochemicals are sometimes above chemicals.

The oleochemicals are an increasingly attractive alternative to individual industries since it is a fairly friendly environment and its cost-effective means and also meets the highest expectations and therefore we offer different markets a wide range of products to develop all kinds of goods and industrial goods. Glycerin is undoubtedly one of the most important and potent substances oleochemical market.
