摘要:
以活性炭为载体,采用浸渍法制备了系列负载型硫酸锆催化剂ZS/AC,用FT-IR、XRD、N2吸附-脱附、EDS等技术对催化剂进行了表征.结果表明,负载量较低时,硫酸锆能很好地分散在载体上;负载量≥40%时,有四水硫酸锆晶相出现.该系列催化剂对乙二醇单乙醚与乙酸的酯化反应有很高的催化活性,且对目标产物乙二醇单乙醚乙酸酯的选择性为100%.在最佳的负载量和反应条件下,乙二醇单乙醚的转化率高达97%,极具工业应用价值.
Abstract:
A ser ies of activa ted carbon-suppo rted zircon ium sulfate cata ly sts, ZS /AC, w ere prepared by im pregnation. The cata lysts w ere character ized by in frared spec troscopy ( FT-IR), X- ray d iffraction ( XRD), N2 adso rption-desorption and X-ray ene rgy d ispersive spectrome try ( EDS). Itw as found that zircon ium sulfa te could bew e ll d ispersed on the support at lowe r load ing leve,l but ex isted partia lly as sm all agg lom erate crysta lline pa rtic les at loading higher than 40%. These cata ly sts exh ib ited ex ce llent cata ly tic perfo rmance for ester ification of 2- ehoxy ethano lw ith acetic ac id, and the selectiv ity to 2-ehoxyethano l aceta tew as 100%. Under optim al lo ad ing level and reaction cond itions, the conve rsion o f 2- ehoxye thano l is as h igh as 97%, prom ising for industr ial applica tion
