Alpha-phenyl ethyl alcohol is important raw material;It is widely used in fragrance in fragrance production to reconcile, as various essential oils due to flowery odour
Main component.The effective ways of alpha-phenyl ethyl alcohol synthesis are usually to be changed into benzyl carbinol by hydrogenation of acetophenone reduction.Due to benzene second
The inductive effect of phenyl ring and c h bond and carbonyl keep carbonyl electronegativity higher, are easily accepted by there is σ-π hyperconjugation in ketone
Proton, therefore carbonyl hydrogen is easier to carry out.The by-product of hydrogenation of acetophenone is mainly ethylbenzene and benzene ring hydrogenation product.
Catalyst is the key that whole process in hydrogenating reduction, and common heterogeneous catalysis has with Pt, Ru, Pd, Rh etc.
For the noble metal catalyst of active component, nickel-base catalyst, copper-based catalysts etc..Compared to first two catalyst, cupper-based catalyst
Agent activated adoption hydrogen number is less, while it has greater activity to C=O, and lower to C-C key activity, largely presses down
The hydrogenolysis for having made acetophenone improves the selectivity of alpha-phenyl ethyl alcohol.Patent CN107999082A provides a kind of by adding
Enter auxiliary agent salt compounds to improve activity, selectivity and the copper system hydrogenation of acetophenone catalyst to prolong the service life, reaction
2000h acetophenone conversion still is able to be maintained at 98% or more, but needs that the rare earths such as La, Ce gold is added in catalyst preparation process
Belong to, it is at high cost.EP1701877B1 is modified to copper silicon hydrogenation catalyst by alkali and alkaline earth metal ions, limits the pairs such as ethylbenzene
The generation of product, silicon source is added in the form of fumed silica or diatomite causes active component and carrier interaction weak,
It is unfavorable to catalyst strength.CN108043414A proposes a kind of system of the copper-based catalysts of acetophenone liquid-phase hydrogenatin alpha-phenyl ethyl alcohol
Preparation Method significantly suppresses the side reactions such as hydrogenolysis, improves catalytic activity and selectivity, but catalyst need to be passed through difference before
The H of ratio2、N2Gaseous mixture is activated, cumbersome.Therefore development technology is simple, green is cheap, stability and high efficiency plus hydrogen is urged
Agent substitutes traditional hydrogenation catalyst, has important economic value and social benefit.
Amorphous alloy possesses the characteristics such as the easy modulation of structure, coordination height unsaturation, chemical uniformity, eliminates traditional crystalline substance
The activity difference of state catalysis material difference crystal plane structure, keeps active center distribution uniform, property is identical.Amorphous catalysts add hydrogen living
Property than the crystal alloy of same composition be higher by hundred times, and show highly selective, greatly improve the Atom economy of raw material, reduce
The generation of waste, becomes novel environment friendly catalysis material.It is reported in Chinese patent CN1557545A and utilizes chemical reduction method
The amorphous state Ni-Sn-B/SiO of preparation2It is catalyzed hydrogenation of acetophenone alpha-phenyl ethyl alcohol, selectively reaches as high as 97.5%, however nickel
Base noncrystal alloy catalyst is easily oxidized inactivation, is not easy to store;And China's nickel resources only account for the 3.7% of global gross reserves, nickel source
Price is relatively high, is unfavorable for large-scale industrial production.Therefore, exploitation amorphous state copper-based catalysts meet current Chemical Manufacture
Development trend simplifies production process to reduced cost, and it is significant to improve production security.
