Abstract： 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".
