发明名称 Separation of butyraldehyde from ethanol by extractive distillation
摘要 Butyraldehyde cannot be separated from ethanol by conventional distillation or rectification because they form a minimum boiling azeotrope. Butyraldehyde can be readily separated from ethanol by extractive distillation. Effective agents are 2-propanol, m-xylene and dimethylsulfoxide.
