摘要： A process for producing hydroxyalkyl monoacrylate of the present invention, comprises the steps of: reacting acrylic acid or an acrylic acid derivative with alkane diol for esterification and/or transesterification therebetween in the presence of a reaction catalyst comprising a stannoxane compound; recovering said reaction catalyst from a liquid reaction product by extraction; and recycling the recovered reaction catalyst to a reaction system for said esterification and/or transesterification. The process of the present invention is an industrially useful process for producing hydroxyalkyl monoacrylate, which is excellent in reactivity, selectivity for an aimed product, stability of a reaction catalyst used and stability of a reaction substrate and product, and is improved so as to effectively recover and reuse the reaction catalyst.
