  A novel process for purifying Cefmenoxime hydrochloride comprises: 1) adding a solvent wherein Cefmenoxime hydrochloride is insoluble at the temperature less than 30° C. filtering after vigorous stirring, washing the filter cake with a solvent wherein Cefmenoxime hydrochloride is insoluble at a temperature less 20° C., and drying; 2) placing the filter cake into ammonium hydroxide, controlling the pH value less than 9 with a gentle agitation to obtain Cefmenoxime acid solution in ammonium hydroxide, and then filtering out the precipitate; 3) adding hydrochloric acid at a concentration of 0.5-4 mol/L to Cefmenoxime acid solution in ammonium hydroxide slowly and controlling the temperature between 30-60° C. and the final pH between 0.5-3.0, and then cooling down to a minimum of 10° C. and standing still to allow crystallization, filtrating and vacuum drying.
