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 partially 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-羟基脂肪酰腈的方法,包括以下步骤:在碱的存在下,将
烯丙基腈反应,其中
烯丙基腈是烯丙基-2-腈或在反应条件下异构化形成烯丙基-2-腈的
烯丙基腈,与
苯甲醇反应形成3-苄氧基脂肪酰腈加合物,然后在微量HCl的存在下部分加氢加合物,形成3-羟基脂肪酰腈,或完全加氢加合物,形成3-羟基
氨基脂肪烷。
