以三苯基膦改性的铁磁性氧化物担载的钴铑双金属为催化剂,考察了不同极性溶剂对双环戊二烯(DCPD)氢甲酰化反应合成三环癸烷不饱和单醛和三环癸烷二甲醛的影响。结果表明,溶剂的极性对反应速率和目标产物的选择性有较大的影响,三环癸烷不饱和单醛的生成速率随着溶剂极性的增加呈现增加的趋势;三环癸烷二甲醛的反应速率和选择性随着溶剂极性的增加先增加后降低。以极性值为5.4的丙酮作为溶剂时,合成三环癸烷二甲醛最佳,选择性达到了72%。
Using triphenylphosphine-modified ferromagnetic oxide supported cobalt rhodium bimetal as catalyst, the effects of different polar solvents on the hydroformylation of dicyclopentadiene (DCPD) to tricyclodecane unsaturated monoaldehydes And tricyclodecane dicarboxaldehyde. The results showed that the polarity of the solvent had a great influence on the reaction rate and the selectivity of the target product. The formation rate of tricyclodecane unsaturated monoaldehyde showed an increasing trend with the increase of solvent polarity. The reaction rate and selectivity of formaldehyde increase first and then decrease with the increase of solvent polarity. When acetone with a polarity value of 5.4 was used as the solvent, tricyclodecane dicarboxaldehyde was the best and the selectivity reached 72%.
