| titleOfInvention | Method for producing methylene lactones |
| abstract | Kind Code: A1 Various kinds of methylene lactones that can sufficiently inhibit polymerization of methylene lactones when used for distillation at high temperature as a purification step of methylene lactones, are suitably used industrially, and have excellent quality. A method for producing methylene lactones capable of producing A method for producing methylene lactones comprising the steps of synthesizing methylene lactones and purifying them by distillation, wherein the production method comprises a reaction solution obtained by synthesizing methylene lactones as a metal component and / or an impurity. A method for producing methylene lactones, comprising performing a step of purifying the reaction solution by distillation at 70 ° C. or higher in the presence of a polymerization inhibitor after performing the step of removing the acid component.
