采用乙胺预胶体化方法合成了一系列氧化铬层柱苯膦酸锆和氧化铬层柱磷酸锆催化剂,其铬含量达到22.5%～36.5%,比表面为316～462m~2/g,中孔孔容占总孔容的70%以上,孔径集中在2nm左右.氧化铬层柱苯膦酸锆的热稳定性较高.以30%H_2O_2为氧化剂时,这类催化剂对苯、甲苯、乙苯、环己烷、环己烯、正庚烷和正丁醇等有机化合物具有比CrAPO-11和CrMCM-41更高的选择氧化活性. A series of zirconium oxide catalysts were synthesized by ethylamine pre-colloidal method with zirconium phosphide oxide layer and chromium oxide layer column zirconium phosphate catalyst with chromium content of 22.5% -36.5% and specific surface of 316-462m 2 / g, respectively Pore ​​pore volume accounted for more than 70% of the total pore volume, pore size concentrated in the 2nm around the chromium oxide layer column benzene zirconium phosphide higher thermal stability of 30% H_2O_2 as oxidant, these catalysts for benzene, toluene, B Organic compounds such as benzene, cyclohexane, cyclohexene, n-heptane and n-butanol have higher selective oxidation activity than CrAPO-11 and CrMCM-41.
