| description | The invention relates to the technical field of separation methods, and provides a separation method of a byproduct sodium methoxide, which comprises the following steps: S1, by taking dibenzofuran as a raw material and ethylene glycol dimethyl ether as a solvent, adding metal sodium, reacting under the protection of nitrogen, and evaporating ethylene glycol dimethyl ether from reaction liquid; s2, adding a first washing solvent into the product in the step S1, stirring, and filtering to obtain a filter cake; s3, adding a second washing solvent into the filter cake obtained in the step S2, and filtering to obtain a filter cake; and S4, adding a third washing solvent into the filter cake obtained in the step S3, dissolving, and distilling to obtain sodium methoxide. According to the technical scheme, the problems of high production cost, dangerous operation and the like in the sodium methoxide preparation process in the related technology are solved.
