Embodiment Construction

[0027] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0028] see figure 1 , The present invention is equipped with a combustion furnace, a combustion nozzle, a sleeve condenser, a canister, a liquid filter, a heat exchanger, a vacuum pump, a vacuum regulation system, an ignition system, a gas supply and control system, a vacuum test and display device.

[0029]The combustion furnace is the main part of the embodiment of the present invention, and consists of a chassis 1, a furnace body 3 and a furnace cover 7 sealed by an O-ring from bottom to top. Chassis 1 is a stainless steel disc with a round hole in the middle, and the length of the circular passage is increased by welding a round pipe 2 with the same inner diameter as the round hole. There is a groove in the passage, which is fixed and sealed by a rubber gasket and passes through it. combustion nozzle. The height design of the furnace body 3 shou...

Description

technical field [0001] The invention relates to a fullerene combustion synthesis device, in particular to a method for preparing C 60 、C 70 and devices of fullerene derivatives and other carbon clusters. Background technique [0002] Since their discovery in 1985, fullerenes have attracted widespread attention from the scientific community. The synthesis method and potential application value of fullerene have been extensively studied, and the theoretical research has also become more and more in-depth, providing the necessary theoretical guidance for experimental research, making it quickly become a hot field in chemical research. Since the discovery of C60, the exploration of fullerene synthesis methods has never stopped. The synthesis methods of fullerene mainly include laser evaporation graphite method, high frequency resistance furnace heating evaporation graphite method, graphite arc discharge method, solar heating graphite method, naphthalene pyrolysis method, micr...
