Please, experts, advise on methods for separating two substances with similar boiling points

There are currently two substances: benzene (boiling point 80) and vinyl acetate (73). The concentration of benzene is very low, at 300 ppm; but if it is desired to reduce this concentration even further to several dozen ppm, can extraction distillation be used to achieve such a level of purity? Are there any other high-precision separation methods in industry?

If you steam them together, the content of both will be reduced

Steam them together? I don’t quite understand. There is a large amount of vinyl acetate here, with only a small amount of benzene; what is needed is vinyl acetate

Sorry, I misunderstood before.
