The invention relates to a catalyst, a preparation method thereof, and a method for preparing 3-hydroxypropanal. The catalyst has excellent hydrophobicity, can be dissolved in nonpolar solvents, and is insoluble in water. It is suitable for catalyzing the hydration reaction of acrolein to prepare 3‑hydroxypropanal. When the oil-water two-phase process is used to prepare 3-hydroxypropionaldehyde, the recycling degree of the catalyst can be effectively improved, and the loss of the catalyst can be reduced. The single-pass conversion rate of acrolein in this process is high, and the process control is simple, which effectively solves the problem of instability of the acrolein hydration solid catalyst. Easy deactivation, water-soluble catalyst is not easy to separate the problem. |
