| 摘 要： | Amphiphilic ODA/HY and ODA/ Hβ zeolites have been prepared via chemically coating octadecylamine (ODA) with alcohol as solvent. IR and titrimetric results indicate that ODA molecules are chemisorbed on the acidic sites in zeolite, showing the higher thermostability and alcohol-resistance. These am- phiphilic zeolites contain both the hydrophobic and hydrophilic groups, orient at the liquid-liquid phase-boundary in both cyclohexane/water and water/carbon tetrachloride systems, and exhibit the potential to be used in the phase-boundary catalysis and adsorption. No by-products with strong acid- ity are formed in this approach, therefore, it can be used to prepare amphiphilic acidic zeolites with low Si/Al ratio.

| Abstract: | Amphiphilic ODA/HY and ODA/ Hβ zeolites have been prepared via chemically coating octadecylamine (ODA) with alcohol as solvent.
IR and titrimetric results indicate that ODA molecules are chemisorbed on the acidic sites in zeolite, showing the higher
thermostability and alcohol-resistance. These amphiphilic zeolites contain both the hydrophobic and hydrophilic groups, orient
at the liquid-liquid phase-boundary in both cyclohexane/water and water/carbon tetrachloride systems, and exhibit the potential
to be used in the phase-boundary catalysis and adsorption. No by-products with strong acidity are formed in this approach,
therefore, it can be used to prepare amphiphilic acidic zeolites with low Si/Al ratio.
