A device involved in the method structurally comprises a clear liquid delivery pump, a clear liquid storage tank, a turbid liquid storage tank, an interface level meter II, a static mixer, a settling separation tank, a liquid ammonia jet orifice, anti-corrosion conveying pipelines, a reaction kettle, a high-temperature-resistant temperature detector, a feeding port, heating pipes, a temperature alarm, an interface level meter I, a heat exchanger, atwo-way suspension separator, a membrane filter, a turbid liquid delivery pump, a settling pond and control valves, wherein the clear liquid delivery pump is connected with the clear liquid storage tank through one anti-corrosion conveying pipeline; the static mixer is connected with the turbid liquid storage tank through one anti-corrosion conveying pipeline; the two-way suspension separator is connected with the turbid liquid storage tank through one anti-corrosion conveying pipeline; the settling pond is connected with the turbid liquid storage tank through one anti-corrosion conveying pipeline; the heat exchanger is connected with the reaction kettle. The method has an anti-corrosion function, so that the service life of equipment can be prolonged, and the internal reaction condition can be directly known.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a method for preparing a special chromatographic separation medium for separating fullerene and its derivatives. Background technique [0002] In a chemical reaction, the catalyst must keep in good contact with the reaction medium, so mechanical stirring or air blowing stirring is generally used in the reactor to promote the continuous renewal of the surface of the catalyst particles and the surface of the reactants, and the catalyst particles are in a suspended flow state in the reactor . The whole process is continuous production. After the reactants are converted into products, they are discharged from the reactor, and then the catalyst particles are also taken out of the reactor along with the products. In order to recycle the catalyst, solid-liquid separation must be carried out. Filtration and pressure filtration are generally used. During filtration, with the ...
