  • Process for the preparation of cyclohexanedicarboxylic acids
    Patent number: 5286903
    Abstract: Disclosed are processes for the preparation of cyclohexanedicarboxylic acids by the non-catalytic hydrolysis or acidolysis of dialkyl cyclohexanedicarboxylate esters. The processes provide a means for converting dialkyl cyclohexanedicarboxylate esters to cyclohexanedicarboxylic acids without the co-production of solid by-products which present disposal problems.

  • Alkylation reactions catalyzed by gallium-modified titanium dioxide
    Patent number: 5245089
    Abstract: Provided is a process for alkylating aromatic compounds in the presence of mixed oxides of titanium and gallium which have been found to be highly active catalysts for the alkylation of aromatics with alkyl esters, alcohols, olefins and ethers. When the alkyl acceptor is a phenol, the catalysts provide high reaction rates and high selectivity for ortho alkylated products.
