  • Patent number: 4876392
    Abstract: An improved process for preparing ketones by contacting a secondary aliphatic alcohol in the vapor phase with a trimetallic catalyst containing molybdenum, rhenium and a Group VIII noble metal.
    Type: Grant
    Filed: March 28, 1988
    Date of Patent: October 24, 1989
    Assignee: Exxon Research & Engineering Company
    Inventors: Chuen Y. Yeh, Charles Savini
  • Patent number: 4737482
    Abstract: An improved process is provided for forming ketones from the corresponding olefins by vapor phase oxidiation of the olefin in the presence of molecular oxygen and water vapor employing a heterogeneous catalyst comprising rhenium compounds and complexes, optionally containing at least one metal compound or complex selected from the group consisting of Group VIB metals and Group VIII noble metals, and mixtures thereof. 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.
    Type: Grant

  • Patent number: 4560804
    Abstract: An improved process is provided for forming ketones from the corresponding olefins by vapor phase oxidation of the olefin in the presence of water vapor, and optionally in the additional presence of molecular oxygen employing a heterogeneous catalyst comprising at least one member selected from the group consisting of Ce, Nd and La and compounds and complexes thereof, optionally containing at least one metal compound or complex selected from the group consisting of Group VIB metals and Group VIII noble metals, and mixtures thereof. 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.
    Type: Grant

  • Patent number: 4528401
    Abstract: 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.
    Type: Grant
    Filed: July 25, 1983
    Date of Patent: July 9, 1985
    Assignee: Exxon Research & Engineering Co.
    Inventors: Chuen Y. Yeh, Charles Savini
  • Patent number: 4406760
    Abstract: An improved process is provided for treating spent sulfuric acid streams formed in the catalytic hydration of olefins to prepare alcohols, wherein the spent acid stream containing organo-sulfonic acid impurities is treated in an electrolysis zone under conditions sufficient to electrolytically oxidize at least a portion of said organo-sulfonic acid impurities to form partially oxidized organic compounds therefrom and thereby provide a treated sulfuric acid stream of increased thermal stability. The improved process permits continuous operation at levels of total organic carbon in the treated acid which would otherwise be unacceptable and minimizes the substantial operating problems associated with formation of heavy carbon deposits in the process equipment.

  • Patent number: 4219685
    Abstract: Methods for deodorizing lower alcohols such as ethanol and isopropyl alcohol and their oxy derivatives such as ethers and esters are disclosed, including contacting these compounds with a deodorizing contact mass comprising, on a support, metals and/or metal oxides, preferably of the metals of Group IB, VIB and VIII of the Periodic Table, where the metal oxides are at least partially reduced to metal and the deodorizing contact mass has a minimum particle dimension of greater than about 0.254 mm so as to be in a form suitable for use in a fixed bed contacting process. In a preferred embodiment, isopropyl alcohol is deodorized employing such deodorizing contact masses, preferably comprising Group VIII metals such as nickel, iron, cobalt and the like, on a support, so that the contact mass has a surface area less than about 1,500 m.sup.2 per gram.
