    摘要: PROBLEM TO BE SOLVED: To provide a method for producing a polyfunctional (meth)acrylate without causing discoloration or gelation by using a recovered catalyst even after recycling so many times in the case of producing the polyfunctional (meth)acrylate by an ester interchange reaction. SOLUTION: This method for producing the polyfunctional (meth)acrylate is provided by performing the ester interchange reaction of a polyhydric alcohol and an alkyl (meth)acrylate with a tin catalyst under reflux, strong acid-treating the recovered catalyst liquid obtained by extracting the reaction liquid with a hydrocarbon solvent, and using the regenerated catalyst in another ester interchange reaction.

    SOLUTION: The method for recovering molybdic acid comprises: a step (a) of firing the spent hydrogenation catalyst containing Mo at 450-900°C; a step (b) of dispersing the fired spent hydrogenation catalyst in NH
    3 water so that the ratio ((M
    N )/(M
    M )) of the molar number (M
    N ) of NH
    3 to that (M
    M ) of MoO
    3 is within 1.6-3 and heating the catalyst-dispersed liquid at 80-100°C to extract Mo; a step (c) of filtering and separating the catalyst-dispersed liquid into residues and an extracted Mo-containing liquid; a step (d) of adjusting the concentration of MoO
    3 in the extracted Mo-containing liquid to 3-20 wt.% and adjusting the pH of the extracted Mo-containing liquid to 0.2-1.5 by adding an acid to precipitate molybdic acid; and a step (e) of filtering and separating the precipitated material to recover molybdic acid.
