新型N-甲基-N-烯丙基吗啡啉季铵盐类离子液体的合成

The preparation of a new family of ionic liquids via the reaction between N-methyl-N-allyl- morpholinium cations was reported for the first time, and BF-4, PF-6 and （CF3SO2）2N- [bis（trifluoromethanesufonyl）imide, TFSI-]. The cation has an ether bond and is functionalized by allyl . The structure of these compounds were determined by 1H NMR and elemental analysis. Some properties were also presented in this paper.

有机-无机杂多酸盐催化合成油酸甲酯

通过两步法合成了有机无机杂多酸盐:N-甲基-N-丁基吗啡啉磷钨酸盐([Nbmm]3PW12O40),并采用1H-NMR、红外光谱和元素分析对其结构进行表征。以油酸和甲醇进行酯化反应过程为模型反应,考察了[Nbmm]3PW12O40的催化活性。结果表明,当甲醇∶油酸=15∶1(物质的量比),催化剂用量为油酸和甲醇总质量的5%,反应时间6 h,反应温度100℃时,油酸转化率为91.5%(质量分数),且经气质联用仪确认酯化产物几乎均为油酸甲酯。重复性实验表明,该杂多酸盐经回收、真空干燥,重复使用6次后催化活性没有明显降低。
