Abstract

Provided are an industrially advantageous method for separating and purifying isobutylene, the method enabling high-purity isobutylene to be efficiently obtained by a simple process, and a method for producing isobutylene. A method for separating and purifying isobutylene from a reaction gas containing the isobutylene and unreacted isobutanol, comprising: a step (1) of contacting the reaction gas containing the isobutylene and unreacted isobutanol with a first solvent to obtain a first gas containing the isobutylene and a recovered solution containing the unreacted isobutanol; a step (2) of contacting the first gas with a specific second solvent to allow the second solvent to absorb the isobutylene contained in the first gas to obtain an absorption solution containing the isobutylene; and a step (3) of distilling the absorption solution to obtain separated and purified isobutylene. A method for producing isobutylene using the separation and purification method. Fig. 1
