Abstract
The present invention relates to a stripping method capable of recovering, by an environmentally friendly method, a high-purity ester-based compound without concern over the oxidation of an ester-based compound from a mixture containing the ester-based compound. The stripping method has advantages of generating no wastewater, enabling equipment costs to be reduced by simplifying the process, removing concern over the oxidation of an ester-based compound during the process, and enabling the reuse of the components recovered in the process.
