Method of obtaining ketones and sulphonated ion-exchange resin composition associated with that method
A method for preparing ketones in greater yield and selectivity compared to previous catalyzed reactions by acid-catalyzed condensation reaction using a metal-doped polysulfonated ion exchange resin catalyst is disclosed. For example, use of polysulfonated ion exchange resins having at least 5.0 mil...

| description | A method for preparing ketones in greater yield and selectivity compared to previous catalyzed reactions by acid-catalyzed condensation reaction using a metal-doped polysulfonated ion exchange resin catalyst is disclosed. For example, use of polysulfonated ion exchange resins having at least 5.0 milliequivalents sulfonic acid groups/gram catalyst and loaded with metal, such as palladium, provides enhanced yields of methyl isobutyl ketone from the condensation reaction of acetone compared to use of conventional monosulfonated ion exchange resin catalysts. |
