A method for producing a 1,3-dioxolan-4,6-dione compound from a ketone compound and a malonic acid, the method comprising: precipitating a 1,3-dioxolan-4,6-dione compound as a crystal from a mixed solvent comprising a first organic solvent having a dielectric constant of 10 or more and a water, so as to form a precipitated 1,3-dioxolan-4,6-dione compound; and isolating the precipitated 1,3-dioxolan-4,6-dione compound by a solid-liquid separation.
一种从酮化合物和丙二酸制备1,3-二氧杂环己烷-4,6-二酮化合物的方法,包括以下步骤:从包含第一有机溶剂和水的混合溶剂中沉淀1,3-二氧杂环己烷-4,6-二酮化合物的晶体,以形成沉淀的1,3-二氧杂环己烷-4,6-二酮化合物;通过固液分离来分离出沉淀的1,3-二氧杂环己烷-4,6-二酮化合物。
