在没有 CH3I促进下 ,新发现的硫化 Mo/C催化剂对甲醇气相羰化生成醋酸甲酯有高的活性和选择性。室验发现生成羰化产物的最佳温度为 5 73K,醋酸甲酯的时空收率达到 4.33mol/kgcat.h。
In the absence of CH3I promoted, the newly discovered sulfided Mo / C catalyst has high activity and selectivity for the gas phase carbonylation of methanol to methyl acetate. Laboratory found that the optimal temperature for the formation of carbonylation products was 5 73K, and the space-time yield of methyl acetate reached 4.33mol / kgcat.h.
