Product Description

 

Product Description

 
Product Description
P ropylene 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, a cetone, e thyl a cetate and c hloroform, and is soluble in ether. It is soluble in many essential oils, but is not miscible with p etroleum 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 p ropionaldehyde, lactic acid, pyruvic acid and acetic acid.

Application

P ropylene glycol is used for similar applications as other glycols.
P ropylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The use amount in this area accounts for about 45% of the total consumption of p ropylene glycol. Such unsaturated polyester is used extensively for reinforced plastics and surface coatings. P ropylene 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. In the food industry, p ropylene glycol reacts with fatty acid to give p ropylene ester of fatty acids, and is mainly used as food emulsifier; P ropylene glycol is a good solvent for flavorings and pigments. P ropylene glycol is commonly used as solvents, softeners and excipients, etc. in the pharmaceutical industry for the manufacture of various types of ointments and salves. P ropylene glycol is also used as a solvent and a softener for cosmetic since it has good mutual solubility with various spices. P ropylene glycol is also used as tobacco moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking ink. Aqueous solution of p ropylene glycol is an effective anti-freeze agent.
