华法林制备方法及用途

制备方法

1.由苯甲醛与丙酮合成苄叉丙酮，再与4-羟基香豆素缩合制得杀鼠灵。商品有98%原粉，2.5%母粉和0.025毒饵。纯粉由淀粉和原粉均匀混合而成。毒饵由玉米粉等粮食与母粉和警戒色混匀后挤压烘干成条形，也可用母粉和石蜡混合制成蜡块毒饵。2.以水杨酸为原料，先与甲醇进行酯化，然后用醋酐于40℃酰化，再在金属钠作用下酸化合成4-羟基香豆素；或由水杨酸和氯化亚砜经酰化、环化、酸化制得4-羟基香豆素。另由苯甲醛与丙酮在氢氧化钠存在下缩合制得取代丁烯酮。将制得的４羟基香豆素和取代丁烯酮在吡啶中回流，用盐酸酸化至ｐＨ约２，以水杨酸为原料，先与甲醇进行

用途简介

该品为抗凝血型杀鼠剂，在全世界广泛使用，主要用于杀灭小家鼠，大家鼠、褐家鼠等家栖鼠，也可用于灭野鼠。杀鼠灵的作用方式是进入鼠体后表现抗凝血作用，使鼠体内出血而致死。一般投饵后三周内灭鼠率可达90%以上。该品也用作口服抗凝血药。称华法林钠，用于防治血栓栓塞性疾病。抗凝血性杀鼠剂。药剂进入鼠体后表现抗凝血作用，使鼠体内出血而致死。主要用于杀灭小家鼠，大家鼠、褐家鼠等家栖鼠，也可用于灭野栖鼠。
