Problems solved by technology

However, the preparation method also needs to add a large amount of organic solvents, such as 1,2-dichloroethane, etc., and the solvent still needs to be cut off after the end of the isomerization reaction. At the same time, the isomerization reaction time is longer and the amount of catalyst is larger.

Embodiment 1

[0018] Put 100g bridged tetrahydrotricyclopentadiene raw material in a three-necked round bottom flask, then put the three-necked flask into an oil bath, and after reaching 50°C, add an ionic liquid accounting for 10mol% of bridged tetrahydrotricyclopentadiene (1-Butyl-3-methylimidazolium chloride / AlCl 3 , where AlCl 3 The mole fraction is 0.6), stirring continuously for 3h, standing for 10min after the reaction, and separating the product from the ionic liquid by decantation. The product was characterized by gas chromatographic analysis, and the content of pendant tetrahydrotricyclopentadiene in the product was 95.0 wt%.

Embodiment 2-10

[0020] The reaction process of embodiment 2-10 is the same as embodiment 1, and difference is that adjustment reaction condition comprises: reaction temperature, catalyst (type, proportion, consumption) and reaction time, see the table below. The ionic liquids in Examples 8-10 are used repeatedly.

Abstract

The invention discloses a liquid fuel, wherein the content of hanging tetrahydrotricyclopentadiene is greater than 95.0wt%, the freezing point is lower than minus 40 DEG C, and the density is 1.0 g/cm<3>. The invention further discloses a method for preparing the liquid fuel by isomerizing ionic liquid catalytic bridge type tetrahydrotricyclopentadiene.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and in particular relates to a hanging tetrahydrotricyclopentadiene high-density liquid hydrocarbon fuel and a preparation method thereof. Background technique [0002] Aerospace science and technology is an important manifestation of a country's technological level and strength. The flight space of aerospace vehicles covers the range from the atmosphere to outer space, including aircraft, missiles, rockets, near-space vehicles, spacecraft and satellites. The performance of an aircraft, such as range, speed, and load, depends largely on the heat released by fuel combustion. Therefore, increasing fuel density is an important way to improve the propulsion performance of aerospace vehicles. Tetrahydrotricyclopentadiene is a high-density liquid hydrocarbon fuel with excellent performance. It contains various isomers and has a high volume calorific value. It can be used in the aerospace field. The...
