The invention relates to an extractive distillation process for separating a ternary complex azeotropic mixture of cyclohexane/n-propanol/water. The process consists of two extractive distillation towers for separating cyclohexane/n-propanol/water mixture and an extractant recovery tower. Glycerin is used as extractant, cyclohexane/n-propanol/water firstly enters into cyclohexane extractive distillation tower for extraction separation, high purity cyclohexane is obtained at the top of cyclohexane extractive distillation tower, and materials at the bottom of cyclohexane extractive distillation tower enter into n-propanol extractive distillation tower for separation. High purity n-propanol is obtained from the top of the n-propanol extraction distillation tower, and the bottom material enters the extractant recovery tower to separate the extractant from water. The method has the advantages of low energy consumption, simple process, high purity of cyclohexane and n-propanol after separation ...
