Use

Vitamin E is a viscous yellow oil which is distilled at high vacuum. It has max at 294nm (E1cm 1% 71). It is oxygen and light sensitive and is best stored as its stable D--acetate [58-95-7] which is purified by evaporative distillation at b 180-200o(bath temperature)/0.7mm, and has [] D 25 +3.3o (c 5.1, EtOH). It forms needles at -30o and has m 26.5-27.5o, [] D 25 +0.25o (c 10, CHCl3). [NMR: Cohen et al. Helv Chim Acta 6 4 1158 1981, Burton & Ingold Acc Chem Res 1 9 194 1986, Karrer et al. Helv Chim Acta 2 1 520 1938, Robeson J Am Chem Soc, 64 1487 1942, 65 1660 1943.] Of the eight isomers the D--isomer is the most active. [See W.
