Mechanism of Catalytic Organic Solid-Gas Reactions

Abstract

The solid state hydrogenation, deuteration and alkylation of 4-tert-butylphenol have been studied under mild conditions : at room temperature and one bar gas pressure. These catalytic organic solid-gas reactions are completely heterogeneous. Experimental kinetic studies show that the reaction rates depend on the interface nature. Theoretical results are in good agreement with a diffusional process and allow to depicte catalytic solid-gas reactions by a three steps mechanism.
