  Purification Methods It is a viscous liquid which is purified by distillation under high vacuum under N2 or Ar and stored in sealed ampoules in the dark. It is considerably more stable to light and air than the parent unacetylated vitamin. It is insoluble in H2O but freely soluble in organic solvents. All eight stereoisomers have been synthesised. The commercially pure d-tocopheryl acetate (2R,4'R,8'R) has b 180-200o/0.7mm and [] D 20 +3.9o (c 5, EtOH); see above. [Cohen et al. Helv Chim Acta 64 1158 1981, Beilstein 17/4 V 169.]
