摘要：

The acidic sites of aluminophosphate (AIPO-5) and silicoaluminophosphate (SAPO-5) molecular sieves have been investigated using diffuse reflectance i. r. spectroscopy, temperature-programmed desorption (t. p. d. ) of NH//3, and catalytic activitiy in the cracking of cumene and oligomerization of ethylene. The results are compared with those obtained for HZSM-5 and HY zeolites. It is concluded that these zeolites can be arranged in the following decreasing sequence of Broensted acid site strength: HZSM-5 greater than SAPO-5 greater than HY VM GT TH AIPO-5.
