  • Patent number: 7183452
    Abstract: The present invention is directed to novel alkylated aromatic compositions, zeolite catalyst compositions and processes for making the same. The catalyst compositions comprise zeolite Y and mordenite zeolite having a controlled macropore structure. The present invention is also directed to the preparation of the catalyst compositions and their use in the preparation of novel alkylated aromatic compositions. The catalyst compositions of the present invention exhibit reduced deactivation rates during the alkylation process, thereby increasing the life of the catalysts.

  • Publication number: 20070021317
    Abstract: Disclosed are detergent mixtures of alkyl aryl sulfonates of alkaline earth metals derived from linear olefins having a relatively high aryl ring attached on positions 1 or 2 or the linear alkyl chains. The compositions contain a relatively high amount of 1 or 2 tolyl or xylyl isomer of the linear alkylaryl sulfonate and employ a heavy alkyl benzene sulfonate derived from linear olefins and exhibit improved stability and compatibility.
