英文摘要 | A series of bmimbf(4)-templated mesoporous silica gel immobilised se-functionalised ionic liquids have been prepared. the catalysts were characterised by bet, ftir and icp-aes, and the results showed that the content of se increased from 2.7 to 4.76 wt% with pore volume increasing from 0.83 to 1.26 cm(3) g(-1). preliminary tests of this catalyst system on the carbonylation of aniline to afford methyl phenyl carbamate (mpc) indicated that good catalytic activity (higher than 74% aniline conversion with 99% mpc selectivity) could be achieved with higher than 150 mol h(-1) mol(-1) turnover frequency (tof). tof and aniline conversion slightly increased with increasing the content of se from 2.7 to 3.0 wt%, then decreased when the content of se increased to more than 3.0 wt%, this suggested that 2.7 to 3.0 wt% se content should be appropriate for mpc synthesis. the appropriate se content could be obtaineded by adjusting the range of pore volume of mesoporous silica gel from 0.83 to 0.85 cm(3) g(-1). in addition, the recycling test indicated that there was almost no deactivation of the catalyst when it was reused four times. |
