%X Shape selective isopropylation products of coal tar naphthalene over different zeolite catalysts have been studied by capillary gas chromatography/mass spectrometry (CGC/MS) combined with computerized library search and manual interpretations of mass spectra. The analytical results have shown that products mainly consisted of some monosubstituted, disubstituted and a few trisubstituted naphthalenes. Except the low activity of HZSM-5 catalyst, all other zeolite catalysts have higher activity. HY and H beta catalytic activities were the highest, and their naphthalene conversions attained to 79.12 and 55.79 percent respectively, but their selectivities for 2-isopropylnaphthalene (beta-IPN), 2, 6-diisopropylnaphthalene (2, 6-DIPN) and 2, 7-diisopropylnaphthalene (2, 7-DIPN) were too low. ZM catalysts had good activity and much better selectivity, especially for ZM4-3, of which its 2,6-DIPN/2,7-DIPN ratio was 2.97. Therefore, some zeolite catalysts are recommended for shape selective isopropylation of coal tar naphthalene.
