Study on Catalytic Synthesis of Isoamyl Acetate by Supported Methanesulfonic Acid

A series of supported solid catalysts are prepared with ceramic ball, activated charcoal,quartz sands and silica gel as catalyst carrier and under the esterification of iso - pentanol and acetic acid. The properties of the catalyst are investigated. The experimental result shows that, the activities of methane - sulfonic acid catalysts with different supports are related to surface characteristics of the support and the solid acid CH3 SO3- /C has a very good catalytic activity in esterification reaction. It has many advantages in comparision with liquid acid which are easy separation of the product;less corrosion and pollution and repeated usage. The total yield of isoamyl acetate reaches 97 % under optimal conditions.
