    A process for preparing morpholine hydrochloride as the precursor of moroxydine hydrochloride includes such technological steps as inputting ammoniumchloride and further adding morpholine and xylene to reactor at temp lower than 100 deg. C, slowly raising temp to 80-110 deg. C, keeping the temp. constant for 30 min, raising temp. to 120 deg. C or more, reaction for 1.5 -3 hr and then cooling to obtain morpholine hydrochloride acceptable by moroxydine hydrochloride. The ratio of morpholine: ammonium chloride: xylene is 1: (0.66-0.70) : (1.3-1.7).
