摘要:
The present invention provides a process for preparing an oxycodone acid adduct, said process comprising hydrogenating an aqueous solution of 14-hydroxycodeinone and an acid to form a solution of the oxycodone acid adduct, wherein the hydrogenation is carried out at one or more temperatures greater than ambient temperature in the presence of a hydrogenation catalyst and hydrogen gas, wherein the solution of oxycodone acid adduct comprises 6α-oxycodol in an amount ≦about 0.800 area % as determined by HPLC.
