    摘要: Dual cure organotin salts of strong organic acids, the use of such salts as catalysts and an improved process for producing the catalysts are provided. The catalysts are capable of effectively catalyzing esterification and transesterification reactions and urethane, silicone, melamine, ester and acrylic forming reactions and can simultaneously catalyze more than one reaction in a mixture of urethane, silicone, amino, ester and acrylic polymer forming reactants to produce a polymer mixture.

    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.
