[0020] 1. Preparation of catalyst

[0021] 1. Graphene

[0022] The carrier of the functionalized graphene catalyst is graphene, which can be prepared by chemical methods, such as oxidative intercalation method combined with ultrasonic separation or thermal expansion method to prepare graphene oxide from flake graphite, and then prepare graphene oxide into graphite by a certain reduction method alkene. For the detailed synthesis method, see N.I. Kovtyukhova et al., the method adopted in (Chem. Mater., 1999, 11, 771–778). Of course, commercially available graphene can also be directly used.

Abstract

The invention relates to a method for preparing alkoxymethyl furfural by catalyzing 5-hydroxymethylfurfural. Etherification reaction is performed on 5-hydroxymethylfurfural (5-HMF) and tert butyl alcohol in the presence of a protic acid catalyst, and the technical key points are as follows: the protic acid catalyst is a functional graphene catalyst; and the functional graphene catalyst takes graphene as a carrier, and an acidic organic functional group with catalytic activity is connected on graphene. A benzene sulfonic acid functional group is chemically grafted to the surface of graphene to prepare the functional graphene catalyst, not only the advantage of the sulfonic acid functional group can be realized, but also the adverse factors of homogeneous catalytic reaction of p-methyl benzene sulfonic acid can be avoided, thereby providing a new chance for catalyzing the etherification reaction of 5-HMF and tert butyl alcohol. The reaction has the advantages of high reaction activity and high product yield, and toluene and other organic solvents do not need to be used for reaction.

Description

technical field [0001] The present invention relates to the field of chemistry and chemical engineering, in particular to a method for preparing a fuel or a fuel additive based on a biomass platform compound as a main raw material component, specifically a method for preparing a fuel or a fuel additive by catalyzing 5-hydroxymethylfurfural (hereinafter referred to as 5-HMF) A method for preparing alkoxymethyl furfural ether by etherification reaction with fatty alcohol. The invention also relates to a preparation method of the functionalized graphene catalyst used for etherification reaction. Background technique [0002] The non-renewability of fossil resources has prompted people to pay attention to biomass energy. 5-HMF is a renewable industrial feedstock that can be produced in large quantities from the dehydration of glucose or fructose. Glucose is the main component of plants and also the structural unit of cellulose. Glucose can be obtained by hydrolyzing cellulose,...
