Process for synthesizing phenylethanolamine additive of feed

Abstract

A feed additive N-[2-(4-hydroxyphenyl)-2-hydroxyethyl]-1-methyl-3-(4-hydroxyphenyl) propylamine hydrochloride is prepared through direct aminohydrogenation of bilberry-seed ketone to obtain 1-methyl-3-(4-hydroxyphenyl)-propylamine, further reaction with omage-bromo-p-hydroxy-phenylketone, and catalytic hydrogenating reaction of the resultant. 以复盆子酮直接氨氢化制得1－甲基－3－(4－羟基苯基)－丙胺、再与ω-溴-对羟基苯乙酮反应，将所得产物再进行催化氢化反应，制得结构式如下的N－[2－(4－羟基苯基)－2－羟基乙基]－1－甲基－3－(4－羟基苯基)丙胺盐酸盐，它是一种优良的饲料添加剂。
