呋喃-2,3,4,5-四羧酸简介

In chemistry, furantetracarboxylic acid is an organic compound with formula C 8H 4O 9, or (C4O)(-(CO)OH)4, which can be viewed as deriving from furan C 4H 4O through replacement of the four hydrogen atoms by carboxyl functional groups -(CO)OH.
By removal of four protons, the acid is expected to yield the anion C 8O4− 9, furantetracarboxylate, which is one of the oxocarbon anions (consisting solely of oxygen and carbon. By loss of 1 through 3 protons it forms the anions C 8H 3O− 9, C 8H 2O2− 9, and C 8H 1O3− 9, called respectively trihydrogen-, dihydrogen-, and hydrogenfurantetracarboxylate. The same names are used for the corresponding esters.
The acid can be obtained by from dioxalylsuccinate.
The salt rubidium trihydrogenfurantetracarboxylate RbH 3C 8O 9 crystallizes as white needles.
