间氯苯乙酮是一种有机中间体,可通过苯甲酰氯为初始原料制备得到,并用于合成2,3’-二氯苯乙酮。
制备第一步反应:以无水乙醚为溶剂、四氯化碳为引发催化剂,在常压和20℃~35℃下,使用镁、无水乙醇与丙二酸二乙酯加热回流2~4小时,制得乙氧镁基丙二酸二乙酯。丙二酸二乙酯的转化率可达85%~90%。
第二步反应:以无水乙醚为溶剂,在常压和30℃~35℃下,由乙氧镁基丙二酸二乙酯与间氯苯甲酰氯反应生成间氯苯甲酰丙二酸二乙酯。间氯苯甲酰氯转化率达到90%,选择性可达85%。
第三步反应:在硫酸水溶液中,在常压和90℃~110℃温度下加热回流3~5小时,由间氯苯甲酰丙二酸二乙酯水解和脱羧生成间氯苯乙酮。水解脱羧率几乎达到100%。经精馏分离后可获得含量≥99%的间氯苯乙酮,产品得率可达75%~85%。
淡黄色液体
用途用作医药合成原料,主要用于合成治疗癫痫药物卡马西平等;同时也可用于精细化工、农药等中间体。
