【 Application 6 】
Glycerin is an important basic organic raw material, which is widely used in industry, medicine and daily life. At present, there are about 1700 kinds of uses, mainly used in medicine, cosmetics, alkyd resin, tobacco, food, drinking acid resin, cellol and explosives, textile printing and dyeing. The consumption of glycerol in alkyd resin, Cellol and explosives showed a decreasing trend. However, applications in medicine, cosmetics, and food will continue to grow. In the past few years, the consumption of glycerin in China was 35.7% for coatings, 32.6% for toothpaste, 4.8% for cosmetics, 6% for cigarettes, 5.9% for medicine, 4.8% for polyethers, and 10.2% for other products. In the manufacture of drugs and cosmetics, glycerin is widely used in preparation of various preparations, solvents, hygroscopic agents, antifreeze agents, sweeteners. The synthesis of glycerol and p-nitroaniline gives the meso-6-nitroquinoline. Monostearin obtained by acidizing glycerol with stearin is an excipient used as a substrate for hydrophilic ointments. Glycerol is eliminated to obtain acrolein, which has been used to produce methionine and glutaraldehyde. Potassium glycerophosphate, sodium glycerophosphate and calcium glycerophosphate prepared from glycerol and phosphoric acid are used as nutritional drugs. The intermediate monochloropropanediol can be obtained by chlorination of glycerol, which is used in the production of proxyfylline and guaiacol glycerol ether. Glycerol participates in the cyclization and condensation of p-hydroxybenzaldehyde and 4, 6-trihydroxy-3, 5-dimethylbenzenone to obtain rhododendron, an expectorant and cough suppressant. Glycerol condensates with acetone to form 1, 2-isopropylglycerol ether. It is used in the manufacture of sharcinol, a white blood cell enhancing drug. Nitroglycerin is nitrated to produce glycerin trinitrate, the vasodilator nitroglycerin. Glycerol is cyclized with 2, 5-diaminoanisole sulfate to obtain the intermediate 6-methoxy-4, 7-diazepine. Glycerol is also the raw material of the phonetic alphabet 6-methoxy-7-nitroquinoline. Several quinoline derivatives are obtained from glycerol and aromatic primary amines, and such reactions are called Skraup reactions. Another use of glycerin is to make alkyd resins. At present, alkyd resin, acrylic resin, vinyl resin and epoxy resin account for the largest proportion of the world's coatings, among which alkyd resin coatings occupy the first place in the United States and Japan. Glycerol accounts for 42% of the polyols used in alkyd resins. Glycerin is easy to digest and non-toxic, and can be used as a solvent, hygroscopic agent and color carrier in the food industry. In flavoring and coloring foods, glycerin helps shape foods because of its stickiness. In the rapid freezing of food, glycerin can be used as a heat transfer medium directly connected with food. Glycerin is also a lubricant for food processing and packaging machinery. In addition, the use of polyglycerol and polyglycerol and polyglycerol esters in the manufacture of crunchy foods and margarine is increasing year by year. Glycerin is used in tobacco (mainly cigar smoke) as a wetting agent to keep the tobacco moist, prevent embrittleness, and increase the sweetness of the tobacco. Used as a plasticizer in the form of triglyceride triacetate in cigar paper and filter paper. Triacetin accounts for one third of total glycerol consumption in the tobacco industry. During 1970-1986, the average annual growth rate of glycerol production in China was 5.3%, but the average annual growth rate of consumption was 7%. From 1983 to 1986, China imported 52,400 tons of glycerol, with an average annual import of 13,100 tons, accounting for 1/4 of the annual consumption. Glycerol has been recognized as a non-toxic and safe substance, human or animal oral large doses of natural or whole glycerol does not appear harmful effects, human intravenous injection of 5% glycerol solution also shows poisoning phenomenon. The National Institute for Occupational Safety and Health (NIOSH) stipulates that glycerin content in water is harmless to the human body above 1000mg/L.
