Abstract
The present invention relates to a method for producing a 1,3-dioxan-5-one by a short-step and simple method from raw materials that are procurable easily and inexpensively, using, as a raw material, a 1,3-dioxane that is a mixture containing a 1,3-dioxolane. Provided is a method for producing a 1,3-dioxan-5-one, including using a mixture of a compound represented by the following formula (I) and a compound represented by the following formula (II) as a raw material, the method including a step of oxidizing the mixture under an oxidative esterification condition (step 2): wherein, in the formulae (I) and (II), R1 and R2 each independently represent a hydrogen atom or a monovalent hydrocarbon group, or R1 and R2 are bonded to each other to form a divalent hydrocarbon group for constituting a ring structure.
