Properties and uses

Description of properties: Colorless oily liquid. The melting point is 3°C, the boiling point is 258-259°C, 130.5°C (0.39kPa), the relative density is 1.1596 (20/4°C), the refractive index is 1.4301 , and the flash point is 148.8°C. It is miscible with ethanol, ether , chloroform and benzene , slightly soluble in water and carbon disulfide , and has a solubility in water of 5.9g/100ml at 25°C, with a bitter taste.
production methods : derived from glycerol and acetic acid esterification . After preheating the glycerol to 50-60°C, add acetic acid; benzene and sulfuric acid. Heating, stirring and refluxing for dehydration, recovery of benzene after dehydration, adding acetic anhydride , and heating for 4 h. After cooling, neutralize the pH to 7 with 5% sodium carbonate , separate the aqueous layer, and dry the crude oil with calcium chloride . Distill under reduced pressure , collect 128-131 ℃ (0.93kPa) fraction, which is triacetin.

Uses: Used as spice fixative , solvent, toughening agent . It is used in cosmetics; the production of medicines and dyes, as a plasticizer for cigarette filter rods, etc.
