실험 절차

A reactor vessel is charged successively with cis-Tramadol base hydrate (crude) 200 Kg and ethyl acetate 300 l and the contents of the vessel heated to 50° l C. until all solids are in solution. The vessel is then cooled to −5 to 0° C. and the product crystallises. Stirring is continued for two hours and the product is then centrifuged and washed with cold ethyl acetate, 2×25 l. Approximately 165-175 Kg (moist) of cis(+/−) Tramadol base hydrate are obtained from this procedure.
