<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for continuously producing a mono lower alkyl monoalkanol amine in a high yield. <P>SOLUTION: This method for reacting a mono lower alkyl amine with an alkylene oxide in the presence of a catalyst containing a crystalline metallosilicate to produce the mono lower alkyl monoalkanol amine is characterized by including an unreacted raw material recovery process for separating the unreacted mono lower alkyl amine, the alkylene oxide, and the reaction product from the reaction mixture discharged from a reaction zone in the presence of the catalyst by a distillation method and then returning the separated and recovered unreacted mono lower alkyl amine and the separated and recovered unreacted alkylene oxide to the reaction zone, and a purification process for separating the produced mono lower alkyl monoalkanol amine and the produced mono lower alkyl dialkanol amine by a distillation method to recover the mono lower alkyl monoalkanol amine. <P>COPYRIGHT: (C)2007,JPO&INPIT |
