对苯醌四甲酸二酐也称为“1,4-苯醌四甲酸二酐”、“对苯醌四羧酸二酐”或“1,4-苯醌四羧酸二酐”是一种 有机碳氧化物,其分子式为C10O8。这种化合物可视为每分子对苯醌四甲酸脱去两分子后得到的酸酐

常态下,对苯醌四甲酸二酐是一种红色固体,在140以下的干燥空气中可保持稳定。 对苯醌四甲酸二酐不溶于乙醚四氯化碳二氯甲烷二硫化碳溶剂,能与水、乙醇丙酮乙酸乙酯以及四氢呋喃物质发生反应。对苯醌四甲酸二酐能溶解甲基化衍生物中,并赋予溶液橘黄至紫红的颜色,暴露在潮湿空气中可使该溶液变蓝。

历史

对苯醌四甲酸二酐由P. R. Hammond于1963年首先合成,他称该化合物为“最强的π电子受体之一”。[1]
