What is Pentaerythritol tetraacetate?
Chemical properties
white to off-white powder
Safety Profile
Moderately toxic by ingestion.Slightly toxic by intraperitoneal route. When heated todecomposition it emits acrid smoke and irritating vapors
Purification Methods
Crystallise pentaerythritol tetraacetate from hot water, then leach it with cold water until the odour of acetic acid is no longer detectable. It also crystallises from 95% EtOH after dissolving in CHCl3, washing with saturated NaHCO3, then H2O, drying over anhydrous CaCl2 and evaporating. It has been prepared by acetolysis of the tetranitrate in 95% yield [Wolfrom et al. J Am Chem Soc 73 874 1951]. [Breusch & Oguzer Chem Ber 88 1511 1955, LeFèvre et.al. J Chem Soc 16 1958, Beilstein 1 IV 1812, 2 IV 264.]
