Abstract
A method for producing an unsaturated carboxylic ester is provided, which can prevent the raw material compounds and the product of the reaction from splashing and adhering on the inner wall of the reaction vessel and succumbing to polymerization on the inner wall. Specifically, it is characterized by the fact that the difference between the outer periphery of the reaction vessel heated by the heating means and the reaction solution in temperature is not higher than 80° C.
