Physical & Chemical Property:

The scientific name of propylene glycol is "1, 2-propylene glycol". Chemical formula CH3CHOHCH2OH. Molecular weight 76.10. There's a chiral carbon atom in the molecule. The racemate is a viscous liquid with easy hygroscopicity and a slightly spicy taste. Specific gravity 1.036(25/4℃), freezing point -59℃. Boiling point 188.2℃, 83.2℃(1,333 paras), mixed in water, acetone, ethyl acetate and chloroform, soluble in ether. It can be dissolved in many essential oils, but it is not miscible with petroleum ether, paraffin and grease. More stable to heat and light, more stable at low temperatures. The boiling point of the levosome is 187 ~ 189℃, and the specific rotation [α]D20 ~ 15.0°. Propylene glycol can be oxidized to propionaldehyde, lactic acid, pyruvate and acetic acid at high temperatures.

Application:

Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, the amount of this aspect accounts for about 45% of the total consumption of propylene glycol, this unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol is viscous and hygroscopic, and non-toxic, so it is widely used as hygroscopic agents, antifreeze agents, lubricants and solvents in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol and fatty acid reaction to produce propylene glycol fatty acid ester, is mainly used as food emulsifier; Propylene glycol is an excellent solvent for flavoring and coloring. Propylene glycol is often used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments. Because propylene glycol has good miscibility with various spices, it is also used as a solvent and softener for cosmetics. Propylene glycol is also used as a tobacco humidifier, anti-mold agent, food processing equipment lubricating oil and food marking ink solvent. The aqueous solution of propylene glycol is an effective antifreeze agent.
