The purpose of the present invention is to provide: an acrylate production process which does not require a step of extracting acrylic acid with an organic solvent, enables the increase in concentration of acrylic acid in a solution from which an acrylate is to be recovered, and has excellent acrylic acid recovery efficiency; and an acrylic acid recovery method. This acrylate production process and this acrylic acid recovery method are characterized in that a solution which comprises acrylic acid and/or an alkali metal salt thereof, an alkali metal salt of sulfuric acid and water, has a content of acrylic acid and/or the alkali metal salt thereof of equal to or more than a specific value, and has a specified pH value is separated into two phases, i.e., a phase (an upper phase) containing acrylic acid and/or the alkali metal salt thereof in a larger amount and a phase (a lower phase) containing the alkali metal salt of sulfuric acid in a larger amount.
