[0008] But above these methods also have their respective shortcoming, the one, the productive rate of these methods is not high, if will carry out mass production with these methods, there is still a long way to go
The second is that the equipment tends to be complicated, and it is not suitable for both laboratory preparation and industrial production.
[0014] However, this device has disadvantages such as poor airtightness and the need to keep vacuuming during the reaction process. First, the consumption of expensive high-purity helium is very large; second, because of the large exhaust volume during the reaction process, Do not add chlorine, fluorine and other toxic reactants to the system; third, the synthesized substances flow away with the evacuated airflow, which is inconvenient to collect

Embodiment Construction
[0038] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.
[0039] see figure 1 , The present invention is composed of air intake channel, exhaust channel, air pressure test and display device, liquid sealer, reaction chamber, vacuum pump, water cooling system and circuit parts.
[0040] (1) Intake channel and exhaust channel:
[0041] The inlet passage is a passage provided for introducing various buffer gases and different partial pressures of gases, through which a certain gas required for arc discharge can be introduced, and this gas with different partial pressures can be introduced. The exhaust channel is the channel for exhausting the residual gas after the reaction is completed and the channel for vacuumizing the system.
[0042] Buffer gases such as helium, argon, and nitrogen are introduced through the intake channel. The exhaust channel is used to discharge residual gas and vacuumize. The entire ...

Abstract
The carbon cluster synthesizing apparatus for preparing fullerene, especially preparing C60, C70 and C84 fullerene intermediate in arc process and introducing chlorine and brome to stabilize fullerene intermediate, can form stabilized intermediate chloride and bromide. It is provided with a gas inlet passage including 3 parallel vacuum two-way pistons and their connecting pipeline, a gas exhaust passage including 1 three-way piston and its connecting pipeline, a U-pipe with mercury as the pressure measuring and showing device, two liquid sealing units connected serially in the gas inlet passage and the gas exhaust passage, a reaction cavity set between the two liquid sealing units, a vacuum pump connected via joint to the gas exhaust passage, a water cooling system including an electrode water cooling system and a reaction cavity water cooling system, and a circuit part.
Description
technical field [0001] The invention relates to a device for preparing fullerenes, in particular to a method for preparing C 60 、C 70 、C 84 And by introducing chlorine, bromine and other elements into the device to stabilize the fullerene intermediates in the process of fullerene formation, to form relatively stable intermediate chlorination and bromination products, and to capture the fullerene intermediates role. Background technique [0002] Since the discovery of fullerenes in 1985, the exploration of their synthesis methods has never stopped. As a classic synthetic method, (W. , L D.Lamb, K.Fostiropoulos, D.R.Huffman, Nature 1990, 347:354) invented the arc method, has been the main method of fullerene synthesis. [0003] Although so far, there have been many different options for the synthesis of fullerenes, and some methods have been commercialized. However, researchers of fullerenes have been trying to explore its formation mechanism and explore the yield of ...
