An aminoalcohol is synthesized by reacting a cyclic hemiacetal expressed by Formula 1
(where n is 0 or 1; R1 and R2 are each a hydrogen atom, a monovalent saturated hydrocarbon group which is optionally substituted, or a monovalent aromatic group which is optionally substituted, or R1 and R2 are bonded together into a divalent saturated hydrocarbon group which is optionally substituted; and R3, R4, and R5 are each a hydrogen atom, a monovalent saturated hydrocarbon group which is optionally substituted, or a monovalent aromatic group which is optionally substituted),
with hydrogen and any one of ammonia, a primary amine and secondary amine in the presence of a hydrogenation catalyst.
氨基乙醇是由式 1 所表示的环状半缩醛通过反应合成的
(其中 n 为 0 或 1;R1 和 R2 各为氢原子、任选被取代的一价饱和烃基或任选被取代的一价芳香基,或 R1 和 R2 键合为任选被取代的二价饱和烃基;以及 R3、R4 和 R5 各为氢原子、任选被取代的一价饱和烃基或任选被取代的一价芳香基)、
在氢化催化剂存在下,与氢和氨、伯胺和仲胺中的任一种反应。
