3, 4-Dinitrophthalic acid gave a sensitive violet coloration with glucose when heated in aqueous sodium carbonate. In this color reaction, the acid was reduced to 3-nitro-4-hydroxylaminophthalic acid. 4, 5-Dinitrophthalic acid behaved in the same way as the 3, 4-isomer, and was reduced to 4-hydroxylamino-5-nitrophthalic acid. 3, 5-Dinitrophthalic acid was less sensitive in the reaction, showing a yellow coloration by its reduced substances down to 3-amino-5-nitrophthalic acid.
当在碳酸钠水溶液中加热时,3, 4-二硝基邻苯二甲酸与葡萄糖产生敏感的紫色。在该显色反应中,酸被还原为 3-硝基-4-羟基氨基邻苯二甲酸。 4, 5-二硝基邻苯二甲酸的行为与3, 4-异构体相同,被还原为4-羟氨基-5-硝基邻苯二甲酸。 3, 5-二硝基邻苯二甲酸在反应中不太敏感,由于其还原物质降至3-氨基-5-硝基邻苯二甲酸而呈现黄色。
