Abstract

In continuation of work toward the isolation and identification of vitamin E,¹ the following observations have been made. The inactive product obtained by mild bromination of vitamin E concentrates can be reactivated by boiling with Zn dust and HCl in methanol solution. Vitamin E was not destroyed by the catalytic hydrogenation of concentrates at 200° and 200 atmospheres pressure, but the concentrates, after such treatment, were still unsaturated, as indicated by iodine number determinations. An active concentrate of vitamin E has been prepared from crude cottonseed oil.
