Embodiment 1

[0025] Embodiment 1: the preparation of the fuel containing alkyl adamantane and alkyl decahydronaphthalene

[0026] In a 250mL three-necked flask, add 120g of alkyl tetrahydrodicyclopentadiene and 24g of AlCl 3 , reacted at 60°C for 24h, and the obtained product contained 90.1wt% alkyl adamantane and 9.5wt% alkyl decahydronaphthalene; after testing, the density of the fuel was 0.922g / mL, and the freezing point was -80°C ; Thermal stability test: JFTOT dynamic thermal oxidation tester test temperature is greater than 480 ℃.

Embodiment 2-13

[0028] The preparation conditions of Examples 2-13 and the obtained fuel alkyl adamantane content and alkyl decahydronaphthalene content are shown in Table 1.

[0029] Table 1 Example 2-13

[0030]

[0031]After testing, the densities of the products of Examples 2-13 are all greater than 0.90g / mL, and the freezing points are all lower than -75°C; for thermal stability, the test temperature of the JFTOT dynamic thermal oxidation tester is greater than 480°C.

[0032] The preparation method of the present invention can adjust the reaction conditions according to the performance requirements of the fuel so that the content of one of the components is higher than that of the other, or the fuel with the content of the two components meeting the requirements can be obtained.

The invention discloses a preparation method and application of the fuel containing the alkyl adamantane and alkyl decahydronaphthalene. The fuel has high density, excellent low temperature performance, and excellent high heat stability.

Description

technical field [0001] The invention belongs to the technical field of novel aerospace fuels, and in particular relates to a fuel containing alkyl decahydronaphthalene and alkyl adamantane, its preparation method and application. Background technique [0002] With the development of modern aerospace technology, the speed and range of aircraft have been greatly improved, and at the same time, higher requirements have been put forward for the fuel used. In order to meet the needs of the engine, improving the fuel density, volume calorific value and low temperature performance 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. However, adamantane has a higher melting point, while alkyl-substituted adamantine ...
