Purification method of epoxypropane: A method of separating methanol, methyl formate, and aldehydes from epoxypropane through continuous reaction extraction distillation. Aldehydes include formaldehyde, acetaldehyde, and propanal. An alkaline solution containing ammonia or ammonium salt is added above the feed point of crude epoxypropane. The reflux ratio between the condensate returned to the reaction distillation tower and the purified epoxypropane as the product is selected to be between 1-5, so that the methanol in epoxypropane is below 600ppm, the methyl formate is below 100ppm, and the aldehyde content is below 100ppm
