- W1924047206 abstract "Abstract The copper complex of poly [N-2-ethoxycarbonylethyl)iminotrimethylene] proved to be an interesting catalyst for the oxidative coupling of 2,6-dimethylphenol. Even without the addition of hydroxyl ions, necessary for most other known catalysts, its activity was high. To facilitate separation of catalyst and reaction products, the catalyst was immobilized by simple adsorption on hydrophilic silica. Adsorption experiments showed that total adsorption of the catalyst was possible, but catalytic experiments pointed to an inherent significant loss of catalytic activity after adsorption. This deactivation could be explained by assuming that no active copper complexes can be formed in the adsorption trains. The activity of the immobilized catalysts proved to be independent of their molar mass, which is in accord with the adsorption theory of Scheutjens and Fleer. For both unbound and immobilized catalysts, the Michaelis-Menten type of reaction kinetics was observed. Re-use of the catalyst was unsuccessful due to hydrolysis of the ester groups of the polymer ligand. Efforts to improve the hydrolytic stability by substituting t-butyl ester groups for the ethyl ester groups had the expected result. However, re-use was still unsuccessful because of weaker adsorption, probably due to a shielding of the ester carbonyl groups by the bulky t-butyl groups." @default.
