| 摘要 |
A process for prepg. aldehydes comprises (a) prior prepg. catalyst by reacting rhodium C2-18 carboxylte dissolved in (cyclo) aliphatic or aromatic hydrocarbons with CO and H at 50-100 deg.C under 0.1-1.8 MPa to prep. rhodium complex, and (b) hydroformylating by reacting olefinic unsatd. hydrocarbons with CO and H in the liq. phase at 20- 250 deg.C under 0.1-20 MPa in the presence of previous catalyst, water and triarylphosphine aq. soln.. |
