Preparation method of fullerene

Abstract

The invention relates to a preparation method of fullerene, which comprises the following steps: carrying out discharge synthesis in a synthesis furnace, generating soot containing the fullerene, collecting into a collector for stirring and dissolution, sending into a reaction kettle for heating and stirring, then carrying out centrifugation in a centrifuge, simultaneously sending to a vacuum distillation reactor for distillation and concentration, and recycling solution after distillation; adding remaining solids after drying by distillation into the solution for dissolution, then filtering,introducing filtrate obtained by filtration into another vacuum distillation reactor for distillation and concentration; and carrying out chromatographic separation on a fullerene sample obtained by distillation and concentration and then obtaining a pure product. The method can continuously complete the technical processes of synthesis, reaction, filtration, ultrasound, distillation, liquid inlet, discharge and the like, and prepare the fullerene under the continuous and closed conditions without dust pollution and chemical pollution.

Description

technical field [0001] The invention relates to a preparation process of carbon materials, in particular to a preparation method of fullerene. 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 and so on. Since each step is completed in independent equipment, the operation of each step is separated, so there are problems of dust and organic solvent pollution, and the soot and extracted and separated samples are often exposed to the air, making some airborne The sensitive fullerene sample changes during the experiment, resulting in a low final yield of fullerene, and even a pure sample cannot be isolated. 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 discontinuo...

Problems solved by technology

In this way, when the product of the previous equipment is gradually generated, it cannot be transferred to the next equipment in time for corresponding treatment, which not only reduces the efficiency, but also affects the corresponding treatment effect, and even increases the cost of heat preservation and constant pressure.

If it is transferred in batches, it will increase the labor cost, and also increase the expenses of heat preservation and constant pressure.
