20080262268 | Crystallization Method for Benzphetamine - There is disclosed a method for the crystallization of benzphetamine hydrochloride from an organic medium by the steps of removing water from the system to a very low level and then reducing the temperature of the organic medium to provide crystallization of the acid salt. In the event that crystallization does not occur upon lowering the temperature of the medium, it has been discovered that gentle heating of the organic medium results in crystallization of the acid salt. It has also been discovered that higher temperature crystallization has been provided by removal of methamphetamine from the composition. The crystalline benzphetamine hydrochloride can then be isolated by typical liquid/solid separation means such as filtration or centrifugation. | 10-23-2008 |
20090124833 | Process for the Purification of Benzphetamine Hydrochloride - The present invention relates to the economical and separation of benzphetamine hydrochloride and methamphetamine by liquid extraction. An extraction process employing a suitable organic solvent and water at a pH in the range of from about 6 to about 8 provides excellent removal of the methamphetamine by dissolution in the water phase while the benzphetamine dissolves in the organic phase. Simple separation of the two phases results in separation of the two amines. | 05-14-2009 |
