Embodiment Construction

[0080] The present invention will be described below with specific examples, but the protection scope of the present invention is not limited to these examples.

[0081] 1. Experiment of preparing hydroxycyclopentenone from furfuryl alcohol (influence of catalyst, tank reactor)

[0082] In a 100mL reactor, add 50mL of furfuryl alcohol aqueous solution with a mass concentration of 2%, add a certain amount of alkali catalyst, and react at a certain temperature for a specific time.

[0083] Table 1. Rearrangement activity of different base catalysts

[0084]

[0085] It can be seen from the results in Table 1 that different base catalysts can effectively catalyze the rearrangement reaction of furfuryl alcohol and obtain high yields of hydroxycyclopentenone, among which CeO 2 The effect is slightly worse. But even without adding any catalyst, a yield of 60% of hydroxycyclopentenone can still be obtained under better reaction conditions. The influence of the amount of catalys...

Abstract

The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. The method for preparing JP-10 aviation fuel by taking the furfuryl alcohol as a raw material is totally divided into six reactions as follows: a first reaction of carrying out a rearrangement reaction on a furfuryl alcohol solution in the presence of a base catalyst or under the condition that any catalystis not added to prepare hydroxy cyclopentenone; a second reaction of reacting the hydroxy cyclopentenone and hydrogen under catalysis of a hydrogenation catalyst so as to prepare 1,3-cyclopendiol; a third reaction of dehydrating the 1,3-cyclopendiol to prepare cyclopentadiene; a fourth reaction of carrying out a D-A reaction on the cyclopentadiene to produce dicyclopentadiene; a fifth reaction ofhydrogenating the dicyclopentadiene to produce endo-tetrahydrodicyclotadiene; and a sixth reaction of performing isomerization on the endo-tetrahydrodicyclotadiene to produce hanging type tetrahydrodicyclopentadiene, wherein the prepared hanging type tetrahydrodicyclopentadiene can directly serve as the JP-10 aviation fuel. The invention provides a cheap high-efficiency synthetic method for synthesizing the JP-10 aviation fuel from a lignocelluloses-based platform chemical compound, namely furfuryl alcohol.

Description

technical field [0001] The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. It specifically includes six-step reactions: Reaction 1 is the reaction of furfuryl alcohol solution under the condition of alkali catalyst or without adding catalyst to prepare hydroxycyclopentenone through rearrangement reaction; Reaction 2 is the reaction of hydroxycyclopentenone with hydrogen under the catalysis of hydrogenation catalyst Preparation of 1,3-cyclopentadiol; reaction three is the dehydration of 1,3-cyclopentadiol to prepare cyclopentadiene; reaction four is to generate dicyclopentadiene from cyclopentadiene through D-A reaction; reaction five is dicyclopentadiene Hydrogenation of ene generates bridged tetrahydrodicyclopentadiene; reaction six is ​​the isomerization of bridged tetrahydrodicyclopentadiene to generate hanging tetrahydrodicyclopentadiene, and the obtained hanging tetrahydrodicyclopentadiene can be directly Used as JP-10 aviation fuel...
