PROCESS FOR PRODUCING 2,3-DIMETHYL-2-BUTENE

Title:

PROCESS FOR PRODUCING 2,3-DIMETHYL-2-BUTENE

Document Type and Number:

WIPO Patent Application WO/1994/020439

Kind Code:

A1

Abstract:

A process for producing 2,3-dimethyl-2-butene efficiently by isomerizing 2,3-dimethyl-1-butene using at least one acid selected from the group consisting of sulfuric acid and sulfonic acids. This process allows the use of inexpensive catalysts such as sulfuric acid and sulfonic acids, and also the use of a mixture of propene dimerization products as such in the isomerization without necessity for removing the dimerization catalyst components.
