Reaktionsschritte
D-α-tocopherol acetate (produced by Amakasu Chemical Co. of Japan) is heated in a mixed solution of 50% aqueous sulfuric acid and ethyl alcohol (the ratio of about 1:5) to conduct hydrolysis. With the use of D-α-tocopherol thus obtained, treatment is carried out in the same manner as in Example 1.
