摘要:
An amine producing apparatus includes a reactor that reacts a mono-lower-alkylamine and an alkylene oxide, an unreacted-raw-material-recovery distillation column that separates unreacted raw materials by distillation from a product including unreacted raw materials obtained in the reactor, a non-aqueous distillation column that removes water and a light component by a distillation method from a reactive product from which unreacted raw material have been separated, and a purification and distillation column that separates by distillation a desired reactive product (mono-lower-alkylmonoalkanolamine) and residue (mono-lower-alkyldialkanolamine which is a dimer) from a reactive product from which the water and the light component have been removed.
