Features
Propylene glycol is scientifically named as "1,2-propanediol", and has a chemical formula of CH3CHOHCH2OH and a molecular weight of 76.10. There is a chiral carbon atom in the molecule. Its racemate is a hygroscopic viscous liquid and is slightly spicy. It has a specific gravity of 1.036 (25/4 °C), a freezing point of-59 °C, and a boiling point of 188.2 °C, respectively 83.2 °C (1,333 Pa). It is miscible with water, acetone, ethyl acetate and chloroform, and is soluble in ether. It is soluble in many essential oils, but is not miscible with petroleum ether and paraffin oil. It is relatively stable to heat and light, and is more stable at low temperatures. Its L-isomer has a boiling point of 187 to 189 °C and a specific optical rotation [α] of D20-15.0°. It can be oxidized at high temperatures to propionaldehyde, lactic acid, pyruvic acid and acetic acid.
Functions and Applications
Applications
1.Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. Such unsaturated polyester is used extensively for reinforced plastics and surface coatings.
2.Propylene glycol is excellent in viscosity and hygroscopicity and is non-toxic, and thus is widely used as hygroscopic agent, antifreeze, lubricants and solvents in the food, pharmaceutical and cosmetic industry.
3.In the food industry, propylene glycol reacts with fatty acid to give propylene ester of fatty acids, and is mainly used as food emulsifier; Propylene glycol is a good solvent for flavorings and pigments.
4.Propylene glycol is commonly used as solvents, softeners and excipients, etc. in the pharmaceutical industry for the manufacture of various types of ointments and salves.
5.Propylene glycol is used as a solvent and a softener for cosmetic since it has good mutual solubility with various spices.
6.Propylene glycol is used as tobacco moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking ink.
7.Aqueous solution of propylene glycol is an effective anti-freeze agent.
