四氯苯酞

四氯苯酞用途

为一种防治稻瘟病的保护性杀菌剂。病菌侵入稻株之前施药，能有效地抑制附着于稻株表面的孢子形成，阻止菌丝侵入，因此有良好的防治效果，但若稻瘟病菌侵入稻株后施药，不能阻止孢子发芽或菌丝生长。如防治穗颈瘟，在水稻破口期进行首次喷药，用50%可湿性粉剂15g/100m2对水喷雾，在水稻齐穗期或第1次喷药后7d，进行第2次喷药，残效期达13d。如防治叶瘟，于田间见病斑时喷药，用50%可湿性粉剂15g/100m2对水喷雾，若病情仍在发展，5～7d后再喷1次，防治效果70%～90%。

四氯苯酞制备

苯环氯化 以四氯化碳为溶剂（3320g)，在催化剂存在下，加入邻二甲苯223g(2mol)，混合后通氯反应，控制在60℃以下，反应3h，析出白色结晶；升温至70℃，继续通氯至大部分结晶溶解。
侧链氯化 苯环氯化结束后，稍冷，取出铁催化剂加入三氯化磷20g，在高压汞灯光照下通氯，（也可在偶氮二异丁腈和三氯化磷存在下侧链氯化）于70℃反应7h，蒸出四氯公碳，得产品780g左右。
四氯苯酞的合成 将100g3,4,5,6-α,α,α',α'-八氯邻二甲苯和900g95%的硫酸搅拌混合后，升混至130～140℃，保温5h，至无氯化氢气体逸出，冷至室温，再缓缓倒入冰水中，析出淡黄色结晶，抽滤，水洗、干燥后得四氯苯酞70g左右
