Industrial process for producing glycerol can be divided into two categories: the natural oils as raw materials approach, known as natural glycerin resulting glycerol; propylene as raw materials synthesis, refined glycerine factory in Dongguan, resulting glycerin, commonly known as synthetic glycerol. 4.10.1 natural glycerin production before 1984, full recovery from glycerol byproduct tallow soap in plants and animals. Until now, Guangdong refined glycerine manufacturers, natural oils remains the main raw material glycerol, groups of about 42 percent of natural-product glycerine homemade soap, gentle glycerin manufacturers, 58% derived from fatty acid production. Soap industry, saponification of fats and oils. In the United States and Europe, the annual production of about 950,000 tonnes of glycerine. In the 2000 - 2004 period, gentle glycerin manufacturers, wholesale, only the United States, will annually produce about 350,000 tons of glycerin. [3] When the EU 2003/30 / EU regulations implemented, glycerol production will continue to grow, because the Act requires member states in 2010, 5.75 per cent substitution of fossil fuels with biodiesel. Hydrolysis of fats and vegetable oils [edit] triglycerides found in fats and vegetable oils, triglycerides after alkaline hydrolysis will get a long-chain carboxylic acids, sodium and glycerin, this reaction is also known as saponification.
