Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing isobutylene, the method comprising dehydrating isobutanol in a reactor to obtain isobutylene, wherein the dehydrating occurs in the presence of at least one of an organic acid and an organic acid ester, and wherein the content of the organic acid, the organic acid ester, or both the organic acid and the organic acid ester, is 0.005 to 10% by mass with respect to a total of the mass of the isobutanol, the mass of the organic acid,…
