摘要：

The alkylation of naphthalene with isopropanol was carried out over modified MCM-41, HY and SAPO-5 catalysts. The catalysts were characterized by XRD, IR, sorption techniques and temperature programmed desorption of ammonia. The yields of 2-isopropylnaphthalene were 32.1, 47.2 and 52.6 wt.% at 74.7, 55.9 and 81.0% conversion over HMCM-41, CeMCM-41 and LaKY, respectively. The yields of 2,6-diisopropyl naphthalene were in the range of 8 to 35.3%. (C) 1999 Elsevier Science B.V. All rights reserved.
