Abstract
Esters of female sexual (follicle) hormones are obtained in crystalline form by treating crude hormone oils with alkali, separating neutral substances, subjecting the alkali compound to acylation in aqueous solution and causing the acyl compound to crystallize. Examples describe the preparation of the benzoate by benzoylation and of the acetate by acetylation according to the Schaffen-Baumann method, the crude products being recrystallized from alcohol.
