Dioxalin

Dioxalin is a reaction product of glycerol with oxalic acid at 533 K. Its IUPAC name is 5-(hydroxymethyl)-1,4-dioxane-2,3-dione. Dioxalin readily loses two molecules of carbon dioxide at this high temperature to form allyl alcohol and therefore offers a method for conversion of glycerol to allyl alcohol.^[1][2][3]
