"cancelled.", Glycerol has a ubiquitous use pattern and can be found in industrial, professional and consumer products. Glycerol is used as a constituent in numerous products and as an intermediate in industrial applications for the manufacture of products such as soaps, detergents and glycerol esters. It is found in consumer products such as pharmaceuticals, tobacco, food and drinks and is present in numerous other products such as paints, resins and paper.

This method became available once the high-temperature chlorination of propene to allyl chloride could be controlled properly. The allyl chloride produced is oxidized with hypochlorite to dichlorohydrin, which is converted without isolation to epichlorohydrin by ring closure with calcium or sodium hydroxide. Hydrolysis to glycerol is carried out with sodium hydroxide or sodium carbonate. Epichlorohydrin is hydrolyzed to glycerol at 80 - 200 °C with a 10 - 15% aqueous solution of sodium hydroxide or sodium carbonate at atmospheric or overpressure. The residence time in one or a series of several closed, continuously operating reactors amounts to several minutes or several hours depending on the plant concerned. The yield of dilute (10 - 25%) glycerol solution is > 98%. The solution contains 5 - 10% sodium chloride and less than 2% of other impurities. This aqueous glycerol solution containing sodium chloride is evaporated in a multistage evaporation plant under vacuum to a glycerol concentration of > 75%, precipitated sodium chloride is separated at the same time. The glycerol solution is then distilled under high vacuum (about 0.5 - 1.0 kPa), co-distilled water is separated by fractional condensation. Residual inorganic salts and higher oligomers of glycerol remaining after the evaporation must be worked up further or discarded. The glycerol, practically free of water, is treated further to remove colored impurities and odorous material, this can be performed, for example, with activated carbon., Production from acrolein: ... Propene is oxidized to acrolein, which is then reduced to allyl alcohol (Meerwein-Ponndorf-Verley reduction). The allyl alcohol is epoxidized with hydrogen peroxide, and the resulting glycidol is hydrolyzed to glycerol., Production from propylene oxide: ...
