<p>Disclosed is a process for producing isobutylene from acetone with high selectivity from the early stage of the reaction. Biomass-derived isobutylene is produced by converting acetone that is produced from a biomass to isobutylene. The process for producing isobutylene from acetone is characterized by using at least one compound selected from a zeolite having an acid site that is ion-exchanged by a cation, a zeolite-like substance having an acid site that is ion-exchanged by a cation and mesoporous silica as a catalyst. Alternatively, the process is characterized by using, as a catalyst, a zeolite or a zeolite-like substance in which an acid site is inactivated with an organosilicon compound having a smaller molecular size than the pore diameter of the zeolite or the zeolite-like substance.</p> |
