WebAcetic acid can be readily separated from water by using azeotropic distillation. Acetic acid is difficult to separate from water by conventional distillation or rectification because of the close proximity of their boiling points. Crude, wet cyclohexanone containing cyclohexanol and small amounts of other impurities may be distilled in a batch ... WebFrom my lab: "Cyclohexanol and water form an azeotrope that boils at 98.7 °C. When put through a steam distillation, the azeotrope will start to vapour once it reaches its fixed …
