Abstract

Vitamin A acetate is obtained in a process which comprises reacting vitamin A aldehyde with a complex metal hydride, thereafter reacting the resultant reaction product in situ in its reaction mixture with acetic anhydride and recovering the resulting vitamin A acetate. Suitable hydrides are lithium aluminium hydride, sodium borohydride, potassium borohydride and lithium borohydride.
