Silica gel supported Cu nanoparticles for selective reductive etherification of furfural into isopropyl furfuryl ether
Source abstract
Abstract
Furfural (FF) is one of the important platform molecules of biomass, which can be obtained by hydrolysis from lignocellulose and can produce many high value-added chemicals. In this study, a new 4.5 wt% Cu-supported silica gel (SG) catalyst with dual functions of metal and acid site was prepared by acid-base adsorption impregnation method. Isopropyl furfuryl ether (IPFE) with 80.4 % yield was obtained by one-pot reductive etherification of FF in 2-propanol at 150 °C under 2 MPa H 2. The characterization of the catalyst proved that the Cu synthesized by this method was well dispersed, and the average size of Cu NPs was 3.34 nm. The reduction of FF to IPFE in a one-pot reaction system is deduced as follows: the existence of a hydrogenation-etherification pathway (main path) and an acetalization-hydrogenolysis pathway. The study in this paper provides a reference for the development of non-noble metal hydroetherification catalysts.
