Isopropylation over H-Mordenite

Contrary to molecular sieving, spatioselectivity does not depend on the relative rates of diffusion and reaction, hence both can be easily distinguished changing the crystallite size has no effect on spatioselectivity whereas it increases selectivity by molecular sieving. However, the two types of selectivity may act simultaneously as was shown by Song et al. (42) for naphthalene isopropylation over H-mordenite.
