1,2-propanediol is an organic compound with chemical formula C3H8O2, and is miscible with water, ethanol and various organic solvents. Under normal conditions, it is colorless viscous liquid, almost tasteless, and slightly sweet.
1,2-propanediol is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, plasticizer, and surfactant. Its consumption accounts for about 45% of the total consumption of propylene glycol. This kind of unsaturated polyester is widely used in surface coatings and reinforced plastics. 1,2-propanediol has good viscosity and hygroscopicity, and is widely used as hygroscopic agent, antifreeze, lubricant and solvent in food, medicine and cosmetics industry. In the food industry, 1,2-propanediol reacts with fatty acid to produce propylene glycol fatty acid ester, which is mainly used as food emulsifier; 1,2-propanediol is an excellent solvent for condiments and pigments. Due to its low toxicity, it is used as a solvent for spices and food pigments in the food industry. 1,2-propanediol is commonly used in the pharmaceutical industry as a solvent, softener and excipient for manufacturing various ointments and ointments, and as a solvent for blending agent, preservative, ointment, vitamin, penicillin, etc. in the pharmaceutical industry.
