For green and efficient synthesis of β-amino alcohol compounds,a β-amino alcohol with a large functional group was synthesized using epoxybutane and pentamine as raw materials and its structure was characterized in this paper.It was found that the β-amino alcohol could be efficiently synthesized by the reaction of epoxybutane and pentamine in deionized water solvent.The yield of the β-amino alcohol was about 87%when the molar ratio of epoxybutane to pentamine was 1:15 and the reaction was carried out at room temperature in a deionized water solvent system for 3 h.The ring opening aminolysis of epoxybutane to β-amino alcohol without catalyst was easy to operate and showed good product selectivity,which was an environmentally friendly preparation technology of β-amino alcohol belonging to the category of"green chemistry".
