| 中文摘要: |
| 通过对羰基金属催化乙炔羰基化反应的研究，发现羰基铁具有合成丙烯酸甲酯的催化活性。并分别考察了五羰基铁的用量、CO与C2H2的摩尔比、温度、初始压力等因素对反应的影响，进而，对Fe(CO)5催化反应的活性物种进行了推测。结果表明，以甲醇为溶剂，在140°C，CO压力为4.2MPa、n(Fe(CO)5)/n(C2H2)=0.26条件下，单一的Fe(CO)5能够催化乙炔羰化，丙烯酸甲酯的选择性可达97%。其中，n(CO)/n(C2H2)值越高，产物丙烯酸甲酯的选择性越高。 |
| 英文摘要: |
| Acetylene carbonylation reaction has a preliminary exploration with a variety of metal carbonyl, the result is the iron carbonyl has the catalytically active. The factors of the dosage of catalyst, the molar radio of CO/ C2H2, temperature，initial pressure and the role of CO were studied and the active center has also been speculated．The results of the experiments as follows：n(Fe(CO)5)/n(C2H2)=0.26，the reactant methanol as solvent，the initial pressure is 4.2 MPa and reaction temperature 140 癈 for 6 h．Under this conditions，the selective of methyl acrylate approached 97%．The higher n(CO)/ n(C2H2) is crucial to the high selective of methyl acrylate． |
