Unimolecular 1,2-methyl shift reaction and disproportionation of para-xylene is investigated by means of ab initio guantum chemical calculations. Isolated gas-phase models are used to estimate the optimun volume of the reaction complex. Space filling of the computed models is examined in zeolite Y, Beta and ZSM-5. It is suggested that the shape selectivity effect of zeolite molecular sieves on the disproportination reaction can be associated with the steric conditions of the chemical transformation.
