This invention discloses a method for producing isopentenene by cracking methyl tert-amyl ether. The method includes: mixing the methyl tert-amyl ether cracking reaction product with a certain amount of water to obtain a mixture; separating the mixture into oil and water, with the separated aqueous phase entering a methanol recovery tower and the separated crude isopentenene phase entering a water washing tower for washing; the washed crude isopentenene phase entering an isomerization reactor from the top of the water washing tower to convert 2-methyl-1-butene to 2-methyl-2-butene, and then entering an isopentenene refining tower for product refining to produce qualified isopentenene product; the bottom material of the water washing tower entering the methanol recovery tower; the methanol at the top of the methanol recovery tower being reused, and the fresh water obtained at the bottom being reused. This invention removes most of the methanol from the reaction product through oil-water separation, reducing the amount of subsequent water used for washing, thereby reducing the throughput of the methanol recovery tower and achieving the goal of reducing the operating cost of the equipment.
