This paper reports on a kinetic reaction network developed for the synthesis of oxygenates from synthesis gave over Cs-promoted Cu/ZnO catalysts in a differential reaction regime. The most important carbon- carbon bond forming reactions of the model are linear growth by addition of an oxygenated C{sub 1} intermediate to an alcohol chain that yields linear alcohols and a {beta}-addition aldol condensation type mechanism between an oxygenated C{sub 1} intermediate and an aldehydic C{sub n} intermediate that yields 2-methyl-branched primary alcohols. The most important carbon-oxygen bond forming reaction is a methoxide addition, {eta}{sub 0}, that yields methyl esters. Estimates of the kinetic parameters show that the {beta} addition is faster than linear growth, which results in high selectivities to branched alcohols, i.e., 2-methyl-1- propanol.
