ABSTRACT:
The present invention relates to a method for preparing aldehydes by reacting olefins with a synthesis gas including carbon monoxide and hydrogen, and to an apparatus therefore. More particularly, the present invention relates to a method for preparing aldehydes, characterized by spraying and supplying olefins, synthesis gas including carbon monoxide and hydrogen, and a catalyst composition into an oxo reactor through a nozzle, and to an apparatus therefore. According to the present invention, the hydroformylation efficiency can be improved, thereby obtaining desirable aldehydes with a high yield.
