The scientific name of propylene glycol is "1, 2-propylene glycol". Chemical formula: CH3CHOHCH2OH. Molecular weight: 76.10. There is a chiral carbon atom in the molecule. The racemic compound is a hygroscopic viscous liquid with a slightly pungent taste. Specific gravity 1.036(25/4ºC), freezing point -59ºC. Boiling points: 188.2ºC, 83.2ºC(1,333 Pascals). Chemicalbook is miscible with water, acetone, ethyl acetate and chloroform, and soluble in ether. It is soluble in many essential oils, but not miscible with petroleum ether, paraffin and oils. It is relatively stable to heat and light, and even more stable at low temperatures. The boiling point of the left-handed substance is 187 to 189ºC, and the specific rotation [α] d is 20 to 15.0°. Propylene glycol can be oxidized to propionaldehyde, lactic acid, pyruvic acid and acetic acid at high temperatures.
