3,4-二羟基-2'-氯苯乙酮是合成卡巴克络的关键中间体。卡巴克络又称安络血、肾上腺色素缩氨脲水杨酸钠,主要用于治疗毛细血管通透性增加引起的出血。
化学性质该化合物为结晶体,熔点为173℃。
用途它是止血药“安络血”和拟肾上腺素药物“喘息灵”的中间体。
生产方法生产过程如下:将儿茶酚与氯乙酸加入干燥的反应锅内,升温至60℃并搅拌。在85-90℃下保温0.5小时后,冷却至65℃以下,然后逐步加入三氯氧磷,在60-70℃下反应4小时后再于70-80℃下继续反应4小时。待反应物变稠难以搅拌时,加水升温,于90-100℃条件下进行水解0.5小时。冷却结晶后,冷至10℃以下,甩滤得到固体产物,并用清水洗涤至中性,最终得到2-氯-3',4'-二羟基苯乙酮。
