  • Patent number: 4182909
    Abstract: Novel polymeric compositions and processes for employing the same as autoxidation catalysts in the oxidation of olefins and secondary and tertiary alkylaromatic compounds are provided herein. These novel compositions comprise organometallic compounds wherein the organic compositions comprise organometallic compounds which incorporate in the backbone or on side groups in the polymer polar units capable of binding suitable metal ions which together form the oxidation catalyst.

  • Patent number: 4125736
    Abstract: This invention provides an improved process for the disproportionation of highly alkylated phenols with phenol using an improved magnesium oxide catalyst promoted with tungsten oxide, silica sol, and sodium silicate. The method provides a catalyst having a high reactivity, high surface area, and high crush strength compared to known magnesium oxide, tungsten oxide catalysts. The catalyst is useful in phenol methylation and disproportionation. The effect of silica sol and sodium silicate is synergistic since these materials alone will not catalyze these reactions. Surprisingly, the catalyst will not disproportionate olefins.
