Reactions in condensed matter in nanoporous confines such as in zeolites are controlled by the nature of the active species and the organization of molecules in it. In aqueous phase, hydronium ions catalyze the alkylation of arenes with ethanol. The concentration of hydronium ions is determined by the concentration of aluminum in the zeolite lattice. The rate normalized to hydronium ions is constant for a particular pore size, while also limits the degree of hydration of the hydronium ion. The alkylation rate in aprotic solvents is higher than in aqueous phase because of lower energies of activation on zeolite Brønsted acid sites.
