摘要： A method for generating isobutene, for isomerizing normal butene to isobutene, in which generation of by-products can be infinitely suppressed, and a high yield of isobutene can be achieved. The method for generating isobutene includes isomerizing normal butene to isobutene. In isomerizing, the normal butene is brought into contact with zeolite, and a reaction temperature in isomerizing is in a range from 25° C. to 249° C.

摘要： A method for generating isobutene, for isomerizing normal butene to isobutene, in which generation of by-products can be infinitely suppressed, and a high yield of isobutene can be achieved. The method for generating isobutene includes isomerizing normal butene to isobutene, wherein the normal butene is brought into contact with a basic catalyst in isomerizing. A reaction temperature in isomerizing is preferably in a range from 25° C. to 249° C.
