TECHNICAL FIELD

[0001] The utility model relates to ethylene carbonate production technical field, especially relates to a rectifying column for producing ethylene carbonate. BACKGROUND

[0002] At present, in the production of ethylene carbonate, the rectifying column is used to rectify components, but generally the reaction is insufficient during rectification, so that heavy components and light components are mixed together, and generally the light components are located in the upper layer of the heavy components, and when the rectifying column discharges, it is discharged from the upper part, so that part of the light components is taken out, which seriously affects the quality and the qualified rate of the product.
