1,4,5,8-萘四甲酸下游产品

1,4,5,8-萘四甲酸制备

1、芘法以芘为原料，经氯化、氧化而得。

2、苊法此法有丙二睛法和氨基甲酰氯法。

（1）丙二睛法将氯乙酸经氰化、氨化及脱水制得的氰乙酸酰胺溶于氯苯中，与五氯化磷进行反应得丙二睛，理论收率为77%。将丙二睛与等量的苊加入氯苯中，并加入三氯化铝，同时通入氯化氢，加热反应，即得二亚氨基酮，理论产率为89%。将二亚氨基酮用次氯酸钠和高锰酸钾氧化，即得1,4,5,8-萘四甲酸。理论产率为51.8%。

（2）氨基甲酰氯法在三氯化铝存在下，苊与氨基甲酰氯在氯苯中加热进行反应。反应物先用浓盐酸酸化，再用氢氧化钠水解可得5,6-苊二甲酸，产率63%。5,6-苊二甲酸再经氧化，即得1,4,5,8-苊四甲酸，产率60%。
