Abstract
Aldehydes are prepared in a hydroformylation apparatus by the multiphase hydroformylation reaction of one or more olefins with hydrogen and carbon monoxide, where the continuous phase contains a solvent mixture and the hydroformylation catalyst is present in the continuous phase, at least one olefin is present in the dispersed phase, and the loading factor of the tube reactor is greater than or equal to 0.8.
Claims15
A hydroformylation process comprising:
- reacting, in a tube reactor, a multiphase mixture of starting materials comprising one or more olefins having from 2 to 25 carbon atoms, hydrogen, and carbon monoxide, in the presence of a hydroformylation catalyst,
- wherein said multiphase mixture further comprises a continuous liquid phase and at least one dispersed phase, said catalyst is present in said continuous phase, said continuous phase comprises a solvent mixture, at least one olefin is present in said dispersed phase, said tube reactor has a loading factor which is equal to or greater than 0.8, and wherein at least one component of the solvent mixture comprises a polar organic compound having at least two oxygen atoms.
