摘要
通过对膨润土酸化处理得到活性白土,以活性白土为载体浸渍硫酸铁,可得到Fe2(SO4)3/膨润土固体酸催化剂。以Fe2(SO4)3/膨润土为催化剂,通过正交试验对萘的异丙基化反应工艺条件进行了考察,得到适宜的反应条件为:n(萘)/n(异丙醇)=1.8,n(萘)/n(十氢萘)=7.5,反应温度为260℃,反应时间为6 h,催化剂用量为萘质量的12.5%,并各因素影响萘异丙基化反应结果进行了系统分析。此外,还对催化剂的酸强度、酸度和酸的类型进行了表征。
Fe2（SO4）3/bentonite solid acid catalyst was prepared by the bentonite disposed with H2SO4, and then dipped with Fe2（SO4）3 solution, Isopropylation reaction conditions of naphthalene catalyzed by the Fe2（SO4）3/bentonite catalyst were investigated using orthogonal design experiment method. The experimental results showed the optimum reaction condition is n （naphthalene） / n （ isopropyl alcohol） = 8, n （naphthalene） / n （decahydronaphtyalene） = 7.5, reaction temperature is 260 ℃, reaction time is 6 h, m （catalyst）/m （naphthalene） = O, 125, Meanwhile, the effect factors of isopropylation reaction of naphthalene were analyzed systematically, Furthermore, the Fe2（SO4）3/bentonite catalyst was characterized for sour intensity, sour amounts and sour type using NH3-TPD and FT-IR methods,
