Glycerol is a surový materiál pre výrobu z nitroglycerín, octovú kyselinu glycerol, povrchovo aktívne látky, príchute, alkydy a ester ďasná. It môžem be priamo použitím v nemrznúcou zmesou, kozmetika, atramenty, atď.
It plechovka be použitá ako látka zadržiavajúca vodu (použitá na chlieb a koláč); nosič rozpúšťadlo (použitá v príchuť, pigment a vo voderozpustný konzervačná látka; zahusťovadlo (použité na nápoj a víno formulácia); plastifikátor (cukríky, púšť a mäso výrobok); sladidlo, plyn chromatografický fixačný.
EEC poskytuje môže môže je použité na alkoholické nápoje, cukríky, koláče, povrchová úprava glazovanie, mäso a syr poťahovanie, alkoholické nápoje, pekáreň výrobky, želatína, želatína a iné sladkosti.
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10 percent ) increases the density of a sample so that the sample will layer at the bottom of a gel sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol is an important basic organic raw material, being widely used in industrial, pharmaceutical and daily life. There are about 1700 kinds of applications, mainly for medicine, cosmetics, alkyd resin, tobacco, food, sour resin, explosives, textile printing and dyeing and so on. The demand of glycerol in alkyd resin, celluloid and explosives exhibits a downward trend. But its demand in medicine, cosmetics and food will continue to grow. In previous years, the compositions of glycerol consumption in China include: 35.7 percent in paint; 32.6 percent in toothpaste; 4.8 percent in cosmetics; 6 percent in cigarettes, 5.9 percent in medicine, 4.8 percent in polyether and 10.2 percent for the other. During the manufacture of drugs and cosmetics, glycerol is widely used to prepare a variety of preparations, solvents, moisture, antifreeze and sweeteners. The cyclization of glycerol and p-nitroaniline can generate 6-nitroquinoline. The monostearate obtained from the acidification between glycerol and stearic acid is a kind of excipient, used as the matrix of hydrophilic ointment. Glycerol can generate acrolein by elimination reaction, and has been used to produce methionine and glutaraldehyde. The potassium glycerol phosphate, sodium glycerophosphate, calcium glycerophosphate made from glycerol and phosphoric acid are all used as a nutritional medicine. Chlorination of glycerol can generate the intermediate monochloro-propylene glycol for the production of caffeine and guaiacol glycerol ether. Glycerol can participate in the cyclization and condensation of p-hydroxybenzaldehyde and, 4, 6-trihydroxy-3, 5-dimethyl benzophenone to obtain the expectorant cough medicine Rhododendron. Glycerol can be condensed with acetone to form 1, 2-isopropylidene glyceride. This can be used for the manufacture of shark liver alcohol used for increasing the count of white blood cell. Nitration of glycerol can generate glyceryl trinitrate, namely, vasodilator nitroglycerin. Glycerol can be reacted with 2, 5-diaminoanisole sulfate to give the intermediate 6-methoxy-4, 7-phenanthroline. Glycerol is also a raw material for the midrange marker 6-methoxy-7-nitroquinoline. Several quinoline derivatives were obtained from the reaction between glycerol and aromatic primary amines with such reactions being called skraup reactions. Another major application of glycerol is the preparation of alkyd resin. At present, the resin used in the paint around the world includes mainly alkyd resin, acrylic resin, vinyl resin and epoxy resin, among which, alkyd resin paint ranks first in both the United States and Japan. Glycerol accounts for 42 percent in the polyol used in the alkyd resin. Glycerol is easy to digest and non-toxic and can be used as a solvent, hygroscopic agent and vehicle for the food industry. For the seasoning and coloring food, because the glycerol is sticky, and can therefore contribute to food molding. During the rapid freezing of food, glycerol can be used as a direct medium of heat transfer for food. Glycerol is also a lubricant for food processing and packaging machinery. In addition, the application of polyglycerol and polyglycerol esters during the manufacture of crispy and margarine products is increasing year by year. Glycerol can be used in tobacco (mainly cigars) as a humectant to keep the moisture of the tobacco, to prevent embrittlement, and to increase the sweetness of tobacco. In the case of cigar paper and filter paper, it is used as a plasticizer in the form of triacetin. Glyceryl triacetate accounts for one third of the total consumption of glycerol in the tobacco industry. Between 1970 and 1986, the average annual growth rate of glycerol production in China was 5.3 percent , but the average annual growth rate of consumption in the same period was 7 percent . In 1983 – 1986, China imported a total of 52,400 tons of glycerol with the average annual import of 1.31 million tons, accounting for 1/4 of the annual consumption. Glycerol has been recognized as a non-toxic and safe substance with no harmful effect on human or animal upon oral administration of high-dose of natural glycerol. Intravenous injection of 5 percent glycerol solution to human also causes poisoning phenomenon. The national Institute of Occupational Safety and Health (NIOSH) provides that the glycerol content of water, when being higher than 1000mg/L, is harmless to the human body.
