1,4-Dioxan-2-ones are prepared by contacting carbon monoxide with formaldehyde, a 1,2-glycol, and a catalytic amount of hydrogen fluoride. The products of this reaction are readily converted into diglycolic acids by heating with aqueous caustic in the presence of a nickel catalyst.
1,4-二噁烷-2-酮是通过将一氧化碳与甲醛、1,2-乙二醇以及少量氟化氢催化剂接触而制备的。该反应的产物经加热与水杨酸钠溶液一起在镍催化剂存在下易于转化为二乙二酸。
