The invention provides a method for separating cyclohexene and 1,3-cyclohexadiene by azeotropic distillation. A mixed solution of cyclohexene and 1,3-cyclohexadiene is introduced into an azeotropic distillation tower from the middle of the azeotropic distillation tower, an azeotrope former is also introduced into the azeotropic distillation tower from the middle of the azeotropic distillation tower, overhead gas is condensed by a condenser and enters a tower top decanter for phase splitting and layering, one part of an aqueous phase I flows back to the azeotropic distillation tower through a reflux pump, and the other part serving as a circulating impurity is discharged out of a boundary region; an oil phase I serving as a cyclohexene product is extracted by a cyclohexene product pump; a 1,3-cyclohexadiene and azeotrope former mixture at the tower bottom enters a tower bottom decanter for phase splitting and layering, and an aqueous phase II returns to the azeotropic distillation towerfor recycling by an azeotrope former circulating pump; an oil phase II serving as a 1,3-cyclohexadiene product is extracted by a 1,3-cyclohexadiene product pump, wherein the azeotrope former is water. High-purity cyclohexene and 1,3-cyclohexadiene products can be obtained with the method, utilization rate of by-product heavy oil is increased, operation cost of a device is reduced, and environmental pollution is reduced.
