REACTION APPARATUS FOR PRODUCTION OF ALKANOLAMINE

摘要

SELECTIVE PRODUCTION OF A DIALKANOLAMINE IS ATTAINED BY CONTROLLING THE VOLUME PRECEDING THE ENTRANCE TO A CATALYST BED AND THE TEMPERATURE PREVAILING UNDER RESPECTIVELY FIXED LEVELS SUBSEQUENT TO THE MIXTURE OF AN ALKYLENE OXIDE THEREBY REPRESSING A REACTION OCCURING IN THE ABSENCE OF A CATALYST AND CURBING THE FORMATION OF TRIALKANOLAMINE. @ THE REACTANT FLUID IS PREVENTED FROM GENERATING A CHANNELING BY DISPOSING AN EXPORTABLE STRUCTURE IN A REACTOR THEREBY CREATING THE STATE OF A FALSE SHELL-AND-TUBE TYPE REACTOR. @ THE REACTION INITIATED WITH THE INLET TEMPERATURE SET AT A HIGHER LEVEL THAN THE PRESCRIBED LEVEL AND THE ALKYLENE OXIDE CONCENTRATION SET AT A LOWER LEVEL THAN THE PRESCRIBED LEVEL AND THEREAFTER THE INLET TEMPERATURE AND THE ALKYLENE OXIDE CONCENTRATION ARE GRADUALLY CHANGED TOWARD THE RESPECTIVELY PRESCRIBED LEVELS.
