The present invention provides a process for making 3-hydroxyalkanenitriles comprising the steps of reacting an alkenylnitrile, wherein the alkenylnitrile is an alkenyl-2-nitrile or an alkenylnitrile which under reaction conditions isomerizes to form an alkenyl-2-nitrile, in the presence of a base with benzyl alcohol to form a 3-benzyloxyalkanenitrile adduct and then patrially hydrogenating the adduct in the presence of a trace amount of HCl to form the 3-hydroxyalkanenitrile or fully hydrogenating the adduct to form a 3-hydroxyaminoalkane.
本发明提供了一种制备3-羟基脂肪腈的方法,包括以下步骤:在碱的存在下,将烯基腈反应,其中烯基腈是烯基-2-腈或在反应条件下异构形成烯基-2-腈的烯基腈,与苯甲醇反应形成3-苄氧基脂肪腈加合物,然后在微量HCl存在下部分加氢加合物形成3-羟基脂肪腈,或完全加氢加合物形成3-羟基氨基脂肪烷。
