ABSTRACT:
A process of producing hydroxyalkanal comprises a step of hydrating a raw material, namely, an unsaturated aldehyde, in an aqueous solution in the presence of a lead-carrying heterogeneous acid catalyst promoting the hydration reaction. According to the above method, the lead-carrying heterogeneous acid catalyst curbs the consecutive reaction of the reaction product, namely, hydroxyalkanal. Thus, hydroxyalkanal can be produced with high selectivity at high yield out of a high-concentration unsaturated aldehyde solution. Moreover, the catalyst can be used repetitively for a considerable period of continuous use in a stable manner, thereby further improving the yield of hydroxyalkanal.
