The effects of cerium-modified mordenites coated with trimethylphosphate, trimethyl phosphite and coating liquid A on amination reaction atatmospheric pressure in a fixed bed reactor have been studied. With theestablishment of the relations between the catalytic property and the coatingconditions of coating time, coating temperature and coating concentrationthe suitable preparing conditions were determined Under under thedimethylamine selectivity of the catalyst ACeHM was up to 98. 7 %.
