The invention discloses a separating method of ethyl acetate and cyclohexane. The separating method comprises the following steps of feeding a mixture of the ethyl acetate and the cyclohexane from the middle part of an extractive distillation tower, feeding an extracting agent phenol from the upper part of the extractive distillation tower, and separating out high-concentration cyclohexane from the tower top of the extractive distillation tower; enabling the mixture of the ethyl acetate and the cyclohexane to enter a common rectifying tower from the tower bottom of the extractive distillation tower, separating out the high-concentration cyclohexane from the tower top of the extractive distillation tower, recycling the extracting agent phenol from the tower bottom, and mixing the extracting agent with a fresh extracting agent by a mixer and then returning the mixture to the extractive distillation tower for being recycled. According to the separating method of ethyl acetate and cyclohexane disclosed by the invention, the product obtained by separating is high in purity and high in yield; the extracting agent phenol can be recycled, operation is simple and energy consumption is low. Separating cost is lower than economic value of the recycled ethyl acetate and cyclohexane, and therefore, the separating method has better economic benefits and social benefits.
