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.
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.
