摘要：

Adsorption isotherms of ammonia, trimethylamine, diethylamine, dipropylamine, dibutylamine, ethyldiisopropylamine, and N, N-dimethyl-N′-ethylethylenediamine on HZSM-5 have been measured at 298 and 423 K. The results suggest that the acid sites are mobile at 423 K and that the fraction of strong sorption sites is similar inside and on the exterior surface of the zeolite. © 1990.
