Use

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.
