  • Patent number: 3987104
    Abstract: An improved process for preparing ketones by contacting a mixture of an olefin and steam with a supported catalyst of tin oxide and molybdenum oxide on an inert, thermostable carrier is disclosed, wherein the supported catalyst contains at least one alkali metal or alkaline earth metal compound in an amount, calculated as metal, of 0.01 to 5% by weight, based on the weight of the carrier material. The formation of troublesome by-products is reduced by the use of the alkali metal and/or alkaline earth metal compound, with a resulting improvement in olefin conversion selectivity.
