Embodiment 1

[0026] Embodiment 1: the preparation of tricyclopropyl compound

[0027] (1) Preparation of zinc carbenes

[0028] in N 2 Atmosphere, at -15°C, add 15mL of CH 2 Cl 2 , 15mL of ZnEt 2 (15mmol) reagent, and CF containing 15mmol 3 CH of COOH 2 Cl 2 Solution 15mL, stirred for 20min; continue to add 15mmol of CH 2 I 2 CH 2 Cl 2 Solution 15mL, stirred for 20min to obtain zinc carbene body CF 3 COOZnCH 2 I.

[0029] (2) Cyclopropanation of myrcene to obtain tricyclopropyl compound

[0030] Add 5 mmol of myrcene in CH to the above zinc carbene 2 Cl 2 Solution 15mL, stirred at 25°C for 6h to obtain a mixture containing cyclopropane structure. After analysis, wherein the content of tricyclopropyl compound is 69.8wt% (note: the remaining 31.2wt% is unsaturated one ring and two cyclocyclopropyl compounds), analysis result is as attached Figure 1-2 shown. After separation and purification, the tricyclopropyl compound is obtained, and the analytical results are as attache...

Embodiment 2-15

[0033] Example 2-15 The reaction steps are the same as in Example 1, except that the reaction conditions include: reaction time, reaction temperature, organic acid reagent type, organic solvent type, and the molar ratio of zinc carbene to myrcene, etc. are shown in Table 1; The yield (wt%) of cyclopropyl compound is shown in Table 1.

[0034] Table 1 Example 2-15

[0035]

[0036] The mixture obtained in Examples 2-15 can be used as aerospace fuel after separation and purification or compounded with other high-density aerospace fuels to improve the performance of aerospace fuels.

Description

technical field [0001] The invention belongs to the technical field of novel aerospace fuels, and specifically relates to a tricyclopropyl compound, a preparation method thereof and the use of aerospace liquid hydrocarbon fuels with high calorific value, high energy and high thermal stability. Background technique [0002] The rapid development of the aerospace industry puts forward higher and higher requirements for aerospace fuels. Synthetic fuel has the advantages of high density and high volume calorific value, which can increase the specific impulse of the aircraft to expand the range and payload. Especially for rockets, the fuel needs to have high energy density and good thermal stability to increase the specific impulse of the rocket and provide coolant. For missiles, the fuel needs to have a high density so that it can provide more energy to the missile to extend the range without increasing the volume of the fuel tank. At present, the missile fuels that have been ...
