Collected 121 ° C component 128.3g, yield 96.5%, the Uses. DMAEE is a low odor reactive foaming catalyst, mainly used in rigid packaging foam, also used in molded flexible foam and polyether urethane flexible foam.DMAEE is also an important intermediate, used in polyurethane coatings, surfactants, mine reinforcement and many other fields. Zhongke's organic amine catalyst and curing agent series products will be put into production one after another, and the core catalyst and curing agent products will be used as the basis for the subsequent development of new materials for high value-added polyurethane and epoxy resin by precisely matching the market changes. Integrated manufacturing method of dmae and dmaee in microtubular reactor. A method of integrated preparation of DMAE and DMAEE in microtube reactor is disclosed, which includes the following steps in turn: pumping ethylene oxide and aqueous dimethylamine solution formed by mixing dimethylamine with water as catalyst as materials into the microtube reactor respectively, controlling the molar ratio of ethylene oxide to dimethylamine as 1~2:1; setting the reaction temperature in the microtube reactor as 60~90°C and pressure as 1.3 ±0.2 Pa, and the residence time of the material in the microtubular reactor is controlled to be 15～90s; the effluent from the microtubular reactor is an aqueous solution of DMAE and DMAEE. The method of the present invention has the advantages of high atomic economy, good reaction selectivity, mild reaction conditions, short reaction time, simple catalyst, and simple product separation.
