Abstract

The catalytic activity of zeolite encapsulated cobalt-pathalocyanine for thiol autoxidation varies with the composition of the zeolite support. Different zeolites were compared with carbon supports. The Si Al ratio in the zeolite appears to be the key factor: it determines the hydrophobicity of the support, and it influences the loading of active complex in the zeolite. Two different types of reaction were tested: in an aqueous alkaline medium, the activity increases with hydrophobicity of the support (thus giving carbon a substantial advantage), while in an organic medium, were the commonly used systems are less efficient, sodium Y zeolite is more active than the usual carbon support.
