发明名称 Ethyl acetate production
摘要 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.

主权项 1. A method of purifying an ethyl acetate stream comprising: contacting an inlet stream with a solvent, wherein the inlet stream comprises ethyl acetate and an impurity compound, wherein the impurity compound comprises at least one of a ketone, an aldehyde, or any combination thereof, wherein the impurity compound comprises 2-butanone; transferring at least a portion of the impurity compound from the inlet stream into the solvent to form an extract and a purified product, wherein the extract comprises the solvent and the portion of the impurity compound transferred from the inlet stream; 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.
