| description | The invention discloses a separation method of a polychlorinated pyridine compound and a heat conduction oil mixture, and belongs to the technical field of fine chemical engineering. The method comprises the following steps: cooling a mixture of a polychlorinated pyridine compound and heat conduction oil, adding a free radical absorbent and a diluent into the solid attached with the polychlorinated pyridine compound for dissolving, adding an assistant into the solution, performing heating, performing distilling under reduced pressure, collecting fractions, and dissolving and refining the collected fractions and a polar solvent to obtain a separated product. The method can inhibit and delay the thermal cracking rate of the heat-conducting oil for the mixture of the polychlorinated pyridinecompound and the heat-conducting oil, effectively separates the polychlorinated pyridine compound and the heat-conducting oil, improves the safety, and is suitable for industrial production.
