Industrial grade glycerol production methods: 1/2 volume and diluted with distilled water, and stirred sufficiently, the activated carbon pharmaceutical grade glycerol was added and heated to 60 ~ 70 ℃ decolorization treatment glycerol price, and then vacuum filtered and the filtrate was clear and transparent guaranteed. Control dropping, and the filtrate was added into a good pre-treated with 732 and 717 type strong acid cation resin mixed alkali cation and anion resin column to adsorb remove glycerol electrolyte and aldehydes, pigments, esters and other non-electrolyte impurities. After removing the glycerol solution impurities vacuum distillation glycerol nature, control the vacuum 93326Pa above, the pot temperature 106 ~ 108 ℃, after most of the water evaporated, and then the pot temperature rose to 120 ℃ rapid dehydration, stop heating when no water glycerol, the resulting material shall be finished within the kettle. Complete oxidation of glycerol per gram can produce 4 kilocalories, does not change the blood sugar and insulin levels absorbed by the body. Glycerin is a humectant and sweetener commonly used in the food processing industry, most of them appear in the movement of food and milk substitutes in. Glycerin, 1779 by Sri Lanka firewood Seoul (Scheel) was first discovered, in 1823 it was recognized that contains fat ingredients Chevreul, Greek meaning for sweet, hence the name glycerin (Glycerine). During World War I, because of its raw materials for the manufacture of gunpowder, the yield increase. Glycerin is used as antifreeze automobile and aircraft fuel and oil fields.
