    戊二酸酐又稱膠酸酐,簡稱GA。戊二酸酐為針狀物,比重1.429,熔點41~56℃,沸點287℃,可溶于乙醚、乙醇四氫呋喃等。吸水后為戊二酸。由戊二腈與鹽酸反應升成戊二酸和氯化銨,純制得戊二酸,再于300℃脫水制得戊二酸酐。

  

  用于塑料、橡膠、樹脂、醫藥等的生產和酰胺的制備。戊酸酐用過氧化氫氧化可得過氧化戊二酸。將420mL蒸餾水和221.7g30%的過氧化氫攪拌混合,再加入戊二酸酐342g,劇烈攪拌,維持在15℃反應,補加7.6g過氧化氫繼續保溫1小時,靜置24h,濾出結晶,用水洗滌后紅外燈烘干,得白色粉末狀過氧化成二酸,熔點89-90℃(90℃開始分解)。用作環氧樹脂的固化劑。也是聚合生產一些合成樹脂和合成橡膠的聚合引發劑。

  

  主要用作環氧樹脂的固化劑。也是聚合生產一些合成樹脂和合成橡膠的聚合引發劑。
