Object of the present invention is related to a process for the preparation of Trenbolone Acetate of formula (I):
having a median value (D50) of the particle size distribution comprised in the range from 50 µm to 80 µm, or from 60 µm to 90 µm, or from 90 µm to 250 µm, by means of addition of a seed having a median value (D50) of the particle size distribution comprised respectively in the range from 8 µm to 15 µm, or from 15 µm to 20 µm, or from 20 µm to 90 µm, to a solution of Trenbolone Acetate in a solvent.
本发明的目的是关于制备式 (I) 的
醋酸群勃龙的工艺:
将粒度分布中值(D50)分别为 8 微米至 15 微米,或 15 微米至 20 微米,或 20 微米至 90 微米的种子加入到
醋酸群勃龙在溶剂中的溶液中,该种子的粒度分布中值(D50)范围为 50 微米至 80 微米,或 60 微米至 90 微米,或 90 微米至 250 微米。
