| Abstract: | Isopropylation of naphthalene with isopropanol (IPA) proceeds at 200°C over the large pore zeolites HY, Hβ, H-Mordenite and REY in the presence of N2. Over Hβ, conversion is more in N2 than when cyclohexane is used as solvent or in absence of N2. Conversions and selectivities to diisopropyl naphthalenes fall in the sequence Hβ > REY > HM > HY, but 2,6: 2,7 ratio is greatest with HM.With Hβ, conversion is maximum at 200°C, and increasing the IPA : naphthalene ratio leads to deactivation of the catalyst. |
