【 摘 要 】

Because of the irreplaceable nature of hydroformylation, it has been a hot topic in recent decades. The catalyst for hydroformylation usually takes the transition metal as the center atom. However, the high price of metal restricts the large-scale industrialization of hydroformylation reaction. In this paper, a new type of 1-polyethylene glycol monomethyl ether-3-methyl imidazole rhodium ionic liquid catalyst was used to study the hydroformylation of catalytic octene. The reaction was carried out in a 75mL autoclave. The optimum reaction conditions were obtained by experiments: when the reaction time was 5h, the reaction pressure was 4MPa, and the reaction temperature was 100°C, the conversion of octene reached 90.2%, and the yield of nonylaldehyde reached 70.6%. The new ionic liquid catalyst used in the reaction has the characteristics of "high temperature catalysis, low temperature phase separation". It laid the foundation for the recovery of the catalyst.
