ABSTRACT:
Alkylenebisphenols are converted or cleaved to phenols and alkyl- and/or alkenyl-substituted phenols in good yields by contacting with hydrogen in the presence of a nickel oxide/manganese oxide/metal oxide supported catalyst. In a specific embodiment, bisphenol A is converted to isopropylphenol at high selectivity and high conversion by contacting with hydrogen in the presence of a nickel oxide/manganese oxide/magnesium oxide catalyst.
