  • PROCESS FOR PREPARING 4-CYCLOHEXYL-2-METHYL-2-BUTANOL
    Publication number: 20160311741
    Abstract: A process for preparing 4-cyclohexyl-2-methyl-2-butanol, comprising: a) reaction of styrene with isopropanol at elevated temperature to obtain 2-methyl-4-phenyl-2-butanol, and b) heterogeneously catalyzed hydrogenation of 2-methyl-4-phenyl-2-butanol over a catalyst suitable for ring hydrogenation of aromatics, where the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:below 5 to 1:0.5.
    Type: Application

  • Process for preparing maleic anhydride in a microchannel reactor
    Publication number: 20070270597
    Abstract: The present invention relates to a process for preparing maleic anhydride by heterogeneously catalyzed gas-phase oxidation of a hydrocarbon, which comprises feeding a hydrocarbon-comprising stream and a stream comprising oxygen or an oxygen source into a microchannel reactor and carrying out the reaction to form maleic anhydride in the explosive range in the microchannel reactor comprising the catalyst.
