Abstract

The invention belongs to the technical field of chemical engineering and in particular relates to a method for preparing alpha-phenethyl alcohol by catalyzing acetophenone hydrogenation with a supported amorphous alloy. An amorphous alloy catalyst consists of copper, nickel, boron and a porous carrier material Z, wherein the copper mainly exists in a mode of a Cu-Ni-B amorphous alloy. The preparation method comprises the following step: reducing active components, namely copper and nickel, into a carrier through BH4-. The catalyst is low in raw material price and safe to use, is applied to reactions for preparing phenethyl alcohol through acetophenone hydrogenation, and has good stability and selectivity when being compared with a conventional nickel-based catalyst; and when the acetophenone conversion rate is up to 98% or greater, the selectivity of alpha-phenethyl is up to 97%, and the activity of the catalyst after 300 hours of reactions is still maintained at a high level.

Description

technical field

[0001] The invention relates to the technical field of synthesis of spices and pharmaceutical intermediates, in particular to a method for preparing α-phenethyl alcohol by catalyzing the hydrogenation of acetophenone by a supported Cu-Ni-B amorphous alloy. Background technique

[0002] Aromatic alcohols are important chemical products for the manufacture of medicines and synthetic fragrances. α-phenylethyl alcohol is the most representative compound among aromatic alcohols, and it is an important intermediate in drug synthesis. For example, in the synthesis of ibuprofen, a non-steroidal antipyretic and analgesic drug, α-phenylethyl alcohol is important Raw materials; it is widely used in fragrance production for aroma reconciliation, and it is used as the main component of various essential oils because of its floral fragrance. An effective method for the synthesis of α-phenylethanol is generally to convert acetophenone into phenylethanol by hydrogenation re...
