Device for preparing fullerene

Abstract

The invention discloses a device for preparing fullerene. The device comprises a synthetic furnace, a collector, a reaction kettle, a centrifugal machine, a reduced pressure distillation ultrasonic reactor and an ultrasonic filtering reactor which are connected in turn and among which connection relationships are controlled by valves, and a vacuum pump and an air feeding pump which are respectively connected with the synthetic furnace, the collector, the reaction kettle, the centrifugal machine, the reduced pressure distillation ultrasonic reactor and the ultrasonic filtering reactor and of which connection relationships with the devices are controlled by valves. The device integrates functions such as synthesis, reaction, filtering, ultrasound, distillation, liquid inlet, discharging andthe like, and can prepare the fullerene under continuous, closed, dust pollution-free and chemical pollution-free conditions.

Description

technical field [0001] The invention relates to the preparation of fullerenes, in particular to a fullerene preparation device. Background technique [0002] Usually, the preparation of fullerenes needs to be completed through multiple steps, such as the steps of synthesizing soot, the steps of fullerene extraction, and the steps of high performance liquid chromatography separation, etc. [0003] At present, synthetic soot is generally generated in an arc discharge synthesis furnace, and then the generated soot is collected manually. Since the furnace door needs to be opened during the collection process, the soot is exposed to the air and is sensitive to air. The fullerenes will change rapidly, and the final yield will drop and even the desired fullerene samples will not be obtained; moreover, during the collection process, the dust pollution will be large, which will cause harm to the environment and human health. Therefore, the Shinohara research team in Japan installed ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, in the preparation process of fullerenes, since the operation of each step is separated, there are problems of soot dust and organic reagent pollution, and soot and extracted and separated samples are often exposed to the air, which makes some The air-sensitive fullerene sample changes during the experiment, resulting in a low final yield of fullerene, and even the disadvantage of not being able to separate a pure sample

At the same time, since each step in the preparation process is manually operated, there are many uncertain factors, a large workload, and the test process is discontinuous. There are human factors in the condition control of each step, resulting in poor repeatability of various indicators such as the yield of the final product.
