A method for the production of an esterified product which can prevent the occurrence of a gel-like substance during the separation and removal of the water formed by the reaction in the esterification reaction or during the expulsion of a dehydrating solvent by distillation after the esterification reaction by causing an antigelling agent to act on the distillate and consequently permits efficient production of the esterified product of high quality, and an apparatus therefor are to be provided. To be specific, a method for the production of an esterified product of this invention relates to a method for the production of an esterified product by the esterification reaction of an alcohol represented by the following formula (1): <paragraph lvl="0"><in-line-formula>R1O(R2O)nH (1) </in-line-formula>wherein R1 represents a hydrocarbon group of 1 to 30 carbon atoms, R2O represents an oxyalkylene group of 2 to 18 carbon atoms, providing that the repeating units, R2O, may be the same or different and that when the R2O's are in the form of a mixture of two or more species, the repeating units, R2O, may be added either in a block form or in a random form, and n represents an average addition mol number of oxyalkylene groups and is in the range of 0 to 300, with (meth)acrylic acid, wherein said method comprises acting an antigelling agent on a distillate.
