Embodiment 1

[0020] Put 100g of tetrahydrotricyclopentadiene raw material in a round-bottomed three-neck flask, heat it to 130°C under continuous stirring, add 4g of anhydrous aluminum trichloride, continue stirring for 3h, cool to room temperature after reaction, and use dilute alkali solution respectively The reaction product was washed with water to neutrality, and impurities were removed by distillation to obtain 86 g of the product. The product was analyzed and characterized by gas chromatography, and the content of the component containing the adamantane structure in the product was 85.3 wt%, and the remainder was a mixture of multiple pendant tetrahydrotricyclopentadiene isomers.

Embodiment 2-10

[0022] The steps of the isomerization reaction in each embodiment are the same as those in Example 1, except that the adjustment of the reaction conditions includes: reaction temperature, catalyst dosage and reaction time. See table below.

Abstract

The invention discloses diamantane fuel. The content of alkyl diamantane in the diamantane fuel is higher than 85.0 wt%, the freezing point of the diamantane fuel is lower than -75 DEG C, and the density of the diamantane fuel is higher than 0.98 g / cm<3>; one or a plurality of types of the alkyl diamantane is shown. The invention further discloses a method for preparing the diamantane fuel.

Description

technical field [0001] The invention belongs to the technical field of novel aerospace fuel, and in particular relates to a high-density liquid fuel containing alkyl adamantane and a preparation method thereof. Background technique [0002] With the development of modern high technology, the speed and range of aircraft have been greatly improved. At the same time, higher requirements have been put forward for the fuel used. In order to meet the power requirements of the engine and increase the fuel density, the volume calorific value is the focus of research. . Diamond hydrocarbon is a saturated hydrocarbon composed of a carbon skeleton with a diamond lattice structure. It was first discovered in oil and natural gas condensate, and then people successively synthesized adamantane and diadamantane containing 1, 2, and 3 diamond lattices. and triamantane. Although adamantane has a high melting point, alkyl-substituted adamantine has excellent low-temperature properties (freez...
