【摘要】 采用动态合成法制备了纯度和结晶度高的MCM-22,研究了其对2-乙氧基-3,4-二氢吡喃的水解性能。结果表明,HMCM-22因其独特的结构和表面酸性,对吡喃的水解具有很好的催化性能,时空收率高,稳定性好。在363 K、吡喃／水摩尔比1／7．5、空速(相对于吡喃的液时空速)3．15 h1条件下,连续运转920 h．活性稳定, 平均转化率、选择性和收率分别约99．1％、94．1％和93．2％。更多还原

【Abstract】 The zeolite sample of MCM-22 with high crystallinity was synthesized by the dynamic hydrothermal method. The HMCM-22 was found to be highly active for the hydrolysis of pyran with high yield and stability. The conversion of pyran and the yield of glutaraldehyde were 99. 1% and 93. 2%, respectively, and the activity of MCM-22 was stable for 920 h at the 363 K of temperature, 1/7. 5 of mole ratio of pyran to water, 3. 15 h-1 of LHSV.更多还原
