Carbon cluster synthesizing apparatus

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 synthesis method, the arc method invented by Krtschmer (W. Krtschmer, L D. Lamb, K. Fostiropoulos, D. R. Huffman, Nature 1990, 347: 354) has always been the main method for the synthesis of fullerenes. [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 forma...

Problems solved by technology

[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
