Glycerol Glycerin

CHEMICAL NAME = 1,2,3-propanetriol CAS NUMBER = 56-81-5 MOLECULAR FORMULA = H (T 

3-dichlorohydrin is combined with a sodium or calcium hydroxide solution to produce epichlorohydrin  

In the final reaction stage, epichlorohydrin is hydrolyzed to glycerol using a sodium hydroxide or sodium carbonate base  

In an alternate synthesis, the allyl chloride is hydrolyzed with NaOH to produce allyl alcohol (H2C = CH-CH2-OH). This is then chlorinated to give monochlorohydrin and dichlorohy-drin, which are hydrolyzed with sodium bicarbonate to produce glycerol.

Approximately 27% of glycerol (glycerin) comes from a synthetic process, the hydrolysis of epichlorohydrin. The remaining 73% is made from fats as a by-product of soap manufacture. 

All fats are esters, that is, combinations of fatty acids with the alcohol, glycerol (glycerin). Some fats (butter, lard) are solid at usual room temperature, others are liquid (olive oil, corn oil). But- when heated, the solid fats melt, and, when cooled, the liquid fats turn solid. 

A cold cream sample weighing 8.41 g lost 5.83 g of moisture on heating to 110°C. The residue on extracting with water and drying lost 1.27 g of water-soluble glycerol (glycerin). The balance was oil. Calculate the composition of this cream. 

Glycerol (glycerin, melting point 18°C, boiling point 290°C, density 1.2620, flash point 177°C) is a clear, nearly colorless liquid having a sweet taste but no odor. 

The manufacture of soap (Fig. 1) involves continuous splitting (hydrolysis) and, after separation of the glycerin, neutralization of the fatty acids to soap. The procedure is to split, or hydrolyze, the fat, and then, after separation from the glycerol (glycerin) to neutralize the fatty acids with a caustic soda solution ...

This simplest primary alcohol of the ethylene series, and commonly known as allyl alcohol, is produced from glycerol (glycerin) by a reaction which will be discussed later. It is also produced by the destructive distillation of many organic substances, such as wood, and is therefore found as a constituent of crude wood alcohol. It is a colorless liquid with a strong odor and it boils at 96.6°. It mixes in all proportions with water. By the action of nascent hydrogen, Zn -f H2SO4, it is converted into the corresponding saturated alcohol ... 

Ahronson presented a glycerinated phenol formulation 88% liquid phenol is solubilized in anhydrous glycerol (glycerin) and a few drops of alcohol. This highly concentrated formula, used without occlusion, produces a peel that is not as deep as a peel with Baker-Gordon solution.

Hydrolysis of glycerides (fats) in a basic medium produces glycerol (glycerine) and a mixture of salts of long chained carboxylic acids (fatty acids).
