The specific heat of immersion decreased non-linearly as a function of chain length of alcohol for NaY and 5A. In contrast, the specific heat of immersion passed through a maximum at n-pentanol for ZSM-S. The specific immersion time as a function of chain length of alcohol showed an apparent linear increase in the order 5A > ZSM-S > NaY. NaY showed almost no increase. The effects of sample evacuation temperature and butyl alcohol isomer bulk on the heats of immersion were also investigated. These results were interpreted in terms of molecular accessibility of the wetting liquid into the pores of the zeolites and in terms of the Si/Al ratio of the zeolites.
