A method for preparing an aldehyde including forming a reaction product including an aldehyde by reacting an olefin-based compound with a synthetic gas in a hydroformylation reactor in the presence of a hydroformylation catalyst; introducing the reaction product including the aldehyde to a vaporizer; separating low-boiling point components of the reaction product from an upper part of a vaporizer catch pot included in the vaporizer; separating high-boiling point components of the reaction product from a lower part of the vaporizer catch pot; and recirculating at least a portion of the low-boiling point components separated from an upper part of the vaporizer catch pot back to the vaporizer.

Method for preparing aldehyde and apparatus for preparing aldehyde

Disclosed herein are a heterogeneous catalyst for the preparation of 3-hydroxypropionic acid (3-HPA) from allyl alcohol, and a method for the preparation of 3-HPA from allyl alcohol using the catalyst. In the presence of the heterogeneous catalyst containing gold on a carrier, a liquid-phase reaction is conducted to produce 3-HPA from allyl alcohol at high yield.
