The organic sulfhydryl groups are covalently bonded to the external surface of MTW zeolites through the condensation between siloxane arising from organic fragments with silanol groups on the surface of MTW zeolites, the hybrids contain sulfonic acid group within the external surface of MTW zeolites and an opened mesoporous system in the matrix of MTW zeolites, which provide enough accessible Brùnsted acid sites for the alkylation between phenol with tert-butyl alcohol. Through this methodology it's possible to prepare multifunctional materials where the plenty of mesopores are benefit for the introduction of larger numbers of sulfonic acid groups that contributes to activity during reactions, resulting in high activity(>55%) of MTW-4-SO_(3)H and desired selectivity(>56%) of 2-TBP(2-tert-butyl phenol) in the alkylation between phenol with tert-butyl alcohol.展开更多
Fibrous crystals of boron-containing MTW-type zeolite have been hydrothermally synthesized in B2O3-SiO2-HF-H2O gel system at 170 ℃ in 20 to 28 d by using 1,4-diazabicyclo[2,2,2]octane (DABCO) and me-thylamine as the ...Fibrous crystals of boron-containing MTW-type zeolite have been hydrothermally synthesized in B2O3-SiO2-HF-H2O gel system at 170 ℃ in 20 to 28 d by using 1,4-diazabicyclo[2,2,2]octane (DABCO) and me-thylamine as the co-template, and characterized with XRD, SEM, TEM, HRTEM and SAED. The results of charac-terizations show that B atoms are incorporated into the zeolite framework as tetrahedron of B(OSi)4. The fibrous single crystals of 5—50 mm in length and 100—500 nm in width inter-grow along the c-axis of the zeolite, and the one dimension 12 oxygen ring channels are perpendicular to the fibber axis.展开更多
