| 英文摘要 | Mesoporous sba-15 functionalized with zinc carboxylate (zc/sba-15) was used as a heterogeneous catalyst for the selective synthesis of methyl-4,4'-di(phenylcarbamate) (mdc) from dimethyl carbonate (dmc) and 4,4'-methylenedianiline (mda). zc/sba-15 was prepared in three steps: first, sba-15 grafted with -cn group was synthesized via the conventional one-pot route; then the -cn group was converted into -cooh group in h(2)so(4) solution; lastly, zn(2+) ions were introduced into the material by a facile ion-exchange process. the catalyst zc/sba-15 exhibits high mda conversion (near 100%) and mdc selectivity (about 86.5%) with good recyclability in the mdc synthesis; this may provide a new approach for the non-phosgene synthesis of isocyanates. |
