摘要

合成了一系列酸性的醚基功能化离子液体

对其进行了表征和测定。通过乙腈探针红外光谱法确定了最强酸性的催化剂

并将其用于催化异丁烷与2-丁烯的烷基化反应。结果表明:1-甲氧基乙基-3-甲基咪唑溴氯铝酸离子液体([MOEMIM]Br/AlCl3)在AlCl3摩尔比为0.75时酸性最强

催化烷基化反应效果最佳;在反应温度35℃

异丁烷与2-丁烯体积比10:1的反应条件下催化烷基化反应

可得到C8选择性66.6%的烷基化油;其催化效果远优于非醚基功能化氯铝酸离子液体的催化效果;该催化剂可循环利用。

Abstract

A series of acidic ether functionalized chloroaluminate ionic liquids were synthesized and studied. The catalyst with the highest acidity was screened out by FT-IR spectra using acetonitrile as infrared probe and used to catalyze the alkylation of isobutane with 2-butene. It was proved that the acidity of 1-methoxyethyl-3- methylimidazolium bromide aluminium chloride ([MOEMIM]Br/AlCl3) was the highest when the molar ratio of AlCl3 was 0.75. The high quality alkylate with a C8 selectivity of 66.6%(mass) was obtained at 35℃ with the isoparaffin/olefin molar ratio (I/O) of 10

which was much better than that with non-ether functionalized chloroaluminate ionic liquids. The catalysts could be reused several times without obvious loss of activity.
