Kinetic Study of Thermolytic Reactions of Ethylphenols and Solvent Dodecane
Abstract
The kinetics of thermolytic reactions of three isomeric ethylphenols in solvent dodecane, as well as of o ethylphenol and of dodecane separately, were studied. Pseudo first order rate equations were found to apply satisfactorily to the disappearance of these compounds and related kinetic constants were obtained. A free radical chain reaction mechanism is proposed for dodecane thermolysis and a molecular decomposition mechanism is suggested for the thermolysis of ethylphenols. Experimental observations, including thermal conversion, product distribution, mutual effects of the substrate and the solvent, and the effect of molecular hydrogen on the thermolysis of ethylphenols and dodecane, are explained on the basis of these mechanisms.
