    摘要: An improved process is provided for forming ketones from the corresponding olefins in the vapor phase in the presence of water vapor employing a heterogeneous catalyst comprising a molybdenum disulfide catalyst formed by the thermal decomposition of a thiomolybdate compound. It has been surprisingly found that these catalysts effect the formation of ketones in high selectivities with minimal selectivities to the undesirable carbon dioxide and carbon monoxide by-products.
