Provided is a method for producing isobutylene with a high selectivity by a dehydration reaction of isobutanol. There are provided a method for producing isobutylene by dehydration of isobutanol, in which the dehydration of isobutanol is performed in a state where at least one of an organic acid and an organic acid ester is present in a reaction system, and methods for producing methacrylic acid and methyl methacrylate from the obtained isobutylene.
A composition includes an isomerized polymer containing a structural unit containing an isomerized structure and an isomerized low molecular weight compound, the composition being fluidized by light irradiation from a solid state and being reversibly non-fluidized.
