Title:
β−フェニルエタノールを調製するための反応システム、触媒および方法
Document Type and Number:
Japanese Patent JP6856757
Kind Code:
B2
Abstract:
Disclosed is a method for preparing β-phenylethanol. The method comprises the following steps: (1) reducing a catalyst in a reactor in advance; (2) introducing pre-heated hydrogen gas to warm the reactor to a predetermined temperature; and (3) introducing a raw material styrene oxide to perform a hydrogenation reaction so as to obtain the β-phenylethanol. The catalyst is Ni-Cu/Al2O3nanosized self-assembled catalyst. The reactor is an ultrasonic field micro-packed bed reactor. The method of the present invention enables the selectivity of the β-phenylethanol to reach 99% or more.
