The chloromethylation of benzo-1,4-dioxane in acetic acid in presence of SnCl4, SbCl3, ZnCl2, and SbCl5 catalysts was investigated.The activation energy of the process was found to be 19.6 kcal/mole.The reaction is zero order in chloride ion and first order in the Hammet acidity function.In excess HCl the reaction is described by a second-order equation.The relative activities of the methyl chlorides in the chloromethylation of benzo-1,4-dioxane were determined.
