Abstract:
A method of purifying an ethyl acetate stream comprises contacting an inlet stream with a solvent, transferring at least a portion of the impurity compound from the inlet stream into the solvent to form an extract and a purified product, separating the extract from the purified product, separating the portion of the impurity compound from the extract, forming an impurities stream and a regenerated solvent, and recycling at least a portion of the regenerated solvent to contact the inlet stream. The inlet stream comprises ethyl acetate and an impurity compound, and the extract comprises the solvent and the portion of the impurity compound transferred from the inlet stream.
