探索了1-丁烯氢甲酰化制戊醛的最佳工艺条件。实验中以500 mL 自控高压釜为反应器，采用乙酰丙酮三苯基膦羰基氢铑和三苯基膦作为催化剂体系，考察了二甲苯溶剂中1-丁烯氢甲酰化反应制戊醛的影响因素。结果表明：反应温度、反应时间、搅拌速率、催化剂浓度、膦铑比等多个因素都对氢甲酰化反应有较为明显的影响。在实验室条件下，1-丁烯氢甲酰化反应制戊醛的最佳工艺条件为：反应时间2．5 h、反应温度100℃、反应压力2．5 MPa、搅拌速率200 r/min、膦铑比600、催化剂浓度1．5 mmol/L、1-丁烯用量10 mL、溶剂用量100 mL，此时达到的1-丁烯反应转化率81．7％、产物正异比为8．5、催化剂转化频率（TOF）465 h -1。这些结论为工业生产提供基础实验依据。

The research on 1-butene hydroformylation to produce pentanal is not only helpful to increase the product substitution for plasticizer alcohol,but also can make high value utilization of the abundant C4 resource.The study was carried out with RhH(C5 H7 O2 )(PPh3 )(CO)and triphenyl phosphine as catalyst system and xylene as solvent in 500 mL autoclave.The results show that many factors such as reaction temperature,reaction time,stirring rate, catalyst concentration,[PPh3 ]/[Rh]ratio and so on can affect the reaction obviously.Under the optimum reaction conditions:100 ℃,2.5 MPa,2.5 h,stirring rate 200 r/min,[Rh]=1.5 mmol /L,[PPh3 ]/[Rh]=600,the amount of l-butene 10 mL,xylene solvent 100 mL,the hydroformylation reaction conversion rate,the mole ratio of normal /iso pentanal and TOF were 81.7%,8.5 and 465 h -1 ,respectively.These results are expected to provide a useful experimental basis for the industrial production.
