A method for preparing β-phenylethanol is disclosed. The method includes (1) a step of reducing the catalyst in the reactor in advance, and a step of heating the reactor to a predetermined temperature by introducing a preheated hydrogen gas, and a step of introducing styrene oxide as a raw material. (3) performing a hydrogenation reaction to obtain β-phenylethanol. The catalyst is a Ni—Cu / Al 2 O 3 nano self-assembled catalyst. The reactor is an ultrasonic field type micro packed bed reactor. According to the method of the present invention, β-phenylethanol selectivity can reach over 99%. |
