1. Glycerin is an important organic chemical raw material, which is widely used in many sectors of the national economy. It is an excellent hygroscopic agent, antifreeze agent, lubricant, solvent and co-solvent, and is an important raw material for the production of polyester, explosives, medicine and so on. In the food industry, it can be used as water preservatives (for bread and cakes), carrier solvents (for spices, pigments, non-water-soluble preservatives), thickening agents (for beverages, wine preparation, etc.), plasticizers (for sweets, desserts, meat products, etc.); It can be used as a color carrier in colored food. Glycerin can also be used as a lubricant for food processing and packaging machinery. It is commonly used as softener, viscosity improver and solvent in pharmaceutical and cosmetic manufacturing. In polymer materials, glycerin is often used to produce polyurethane foam, polyether and other raw materials, is an important raw material for the production of alkyd resin and celluloid, especially in the production of alkyd resin paint needs a large amount. It is also widely used in tobacco industry, ceramic industry, leather industry, wood industry and photography. It is also used as fuel for automobiles and aircraft and as an antifreeze in oil fields.
2. Used as analytical reagent, gas chromatography fixed liquid. Measuring boron complexing agent. It is used in the preparation of solvents, lubricants, cosmetics and pharmaceutical industry.
3. Used as a toughening agent for polyvinyl alcohol and starch adhesives, and also used in the manufacture of unsaturated polyester resin, alkyd resin, polyester, propylene glycol epoxy resin, etc. As an important organic chemical raw material, it is widely used in military, food, medicine, daily chemical and other industries, with more than 1700 uses.
Defense industry: Nitroglycerin produced by the interaction of glycerin and nitric acid is a highly sensitive explosive, and glycerin is also used as an antifreeze agent for aircraft fuel.
Food industry: used as solvent, hygroscopic agent and color carrier. 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 in direct contact with food. Glycerin is also a lubricant for food processing and packaging machinery. In addition, the use of polyglycerol and polyglycerol esters in the manufacture of crunchy foods and margarine is increasing year by year.
Pharmaceutical industry: used as softener, viscosity improver and solvent. Glycerol can be used as a sedative, and nitroglycerin is a vasodilator in coronary spasm.
Daily chemical: used in cosmetics, toothpaste, food flavor additives, tobacco anti-drying agent. Plastics industry: Used as a starting agent in the production of polyurethane foam.
Textile printing and dyeing industry: used as lubricant, hygroscopic agent, anti-shrink anti-wrinkle treatment agent, diffusion agent, penetrant and so on. In addition, glycerin is widely used in industries such as ceramics, photography, leather and wood.
4. Glycerol is used in stainless steel polishing solution, trivalent chromium plating solution and electroless copper plating. The zinc cyanide can make the coating smooth and fine, improve the cathode polarization, and make the coating bright. The combination of glycerol and triethanolamine in a certain proportion can be used for bright nickel plating at room temperature.
