Triacetin is prepared by the esterification of glycerin with acetic anhydride.
Triacetin can be derived from the esterification of glycerol and acetic acid. After preheating glycerol to 50-60℃, add acetic acid, benzene and sulfuric acid. Heat and stir for refluxing dehydration, and recycle the benzene. Then add acetic anhydride for heating of 4h. After cooling, the mixture was neutralized with 5% sodium carbonate to pH 7, and the crude layer was dried and the crude oil was dried with calcium chloride. Distill under reduced pressure, collect the 128-131℃(0.93 kPa) fraction, namely glycerol triacetate.
If breathed in, move person into fresh air. If not breathing, give artificial respiration.
Wash off with soap and plenty of water.
Flush eyes with water as a precaution.
Never give anything by mouth to an unconscious person. Rinse mouth with water.
Triacetin solubles in water, miscible with ethanol (96 per cent) and toluene.
An eye irritant. Combustible when exposed to heat, flame, or powerful oxidizers. To fight fire, use alcohol foam, water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Triacetin is stable and should be stored in a well-closed, nonmetallic container, in a cool, dry place.
Triacetin is incompatible with metals and may react with oxidizing agents. Triacetin may destroy rayon fabric.
