In previous work by the authors, aspects of the surface chemistry connected with methyl chloride synthesis over an -alumina catalyst have been examined. This communication considers a role for Group 1 metal salts to modify the catalytic performance of the well characterised -alumina catalyst. Firstly, based on a previously postulated mechanism for the reaction of methanol on -alumina, a mechanism for methyl chloride synthesis over the -alumina catalyst is proposed. Secondly, the validity of the new mechanism is tested by observing how the (i) type and (ii) loading of the Group 1 metal salt may perturb methyl chloride selectivity. The outcomes of these measurements are rationalised with reference to the postulated mechanism. Overall, this study represents an example of how a proposed reaction mechanism has been used to inform and guide a catalyst development strategy for a large-scale industrial process.
