Abstract:
A method for the production of an esterified product which comprises esterifying an alcohol represented by the following formula (1):R.sup.1 O(R.sup.2 O).sub.n H (1)wherein R.sup.1 represents a hydrocarbon group of 1 to 30 carbon atoms, R.sup.2 O represents an oxyalkylene group of 2 to 18 carbon atoms, providing that the repeating units, R.sup.2 O, may be the same or different and that when the R.sup.2 O's are in the form of a mixture of two or more species, the repeating units, R.sup.2 O, 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 in a dehydrating solvent in the presence of an acid catalyst and a polymerization inhibitor, wherein a reaction temperature during the esterification reaction is not higher than 130.degree. C. and a circulation speed of the solvent during the esterification reaction is not less than 0.5 cycle/hour.
