溴苯腈
溴苯腈用途
主要用在禾谷类、亚麻、大蒜、玉米、洋葱、高粱等地，芽后防除苗期阔叶杂草
【用途二】
主要用在禾谷类、亚麻、大蒜、玉米、洋葱、高粱等地，用于芽后防除苗期阔叶杂草
【用途三】
2，6-二溴-4-氰基苯酚是除草剂溴苯腈的中间体。
【用途四】
选择性苗后茎叶处理触杀型除草剂。药剂通过叶片吸收，在植物体内进行极有限的传导，通过抑制光合作用的各个过程迅速使植物组织坏死。主要用于麦田、玉米、高粱、亚麻旱田防除蓼、藜、苋、麦瓶草、龙葵、苍耳、猪毛菜、麦家公、田旋花、荞麦蔓等阔叶杂草。法国Rhone-Poulenc AG已获在我国小麦田上应用的临时登记。可在小麦3～5叶期，阔叶杂草基本出齐，处于4叶期前，用22.5%乳油15～25.5mL/100m2 ，对水4.5kg均匀喷雾，防效90%以上。溴苯腈除草剂还可大幅度提高作物产量，增产幅度为10%～60%。建议使用剂量15mL/100m2 。

溴苯腈制备
溴苯腈的制备 先制备羟基苯甲腈。将13.8g (0.1mol)对羟基苯甲酸、9g(0.15mol)尿素、19.4g氨基磺酸和50mL对甲酚均匀混合后，升温至150℃，保温反应40min，再升温至190℃，并补加3g (0.05mol)尿素，保温反应1h。过滤、洗涤、滤液减压蒸馏，先回收对甲酚，进一步减压得9.6g对羟基苯甲腈，产率81%。
再制备溴苯腈。将11.9g (0.1mol)对羟基苯甲腈、40mL 95%乙醇、15mL水、0.1g浓盐酸混合溶解后，升温至35℃，滴加16.8g (0.105mol)溴。再于1h内滴加4g (0.037mol)氯酸钠和6mL水溶液配制的溶液，滴毕继续反应3h，过滤、水洗、干燥得溴苯腈27g，产率97.5%。
溴苯腈辛酸酯的制备 将108.2g (0.663mol)辛酰氯和48.5g (0.17mol)溴苯腈混合后，升温至130℃，当HCl逸出尚不明显时，再加入48.5g溴苯腈。如此重复1次，直至累积加入145.5g (0.51mol)溴苯腈为止，再反应8h。通氮鼓泡，驱赶HCl和过量的辛酰氯。冷却后得207.2g蜡状固体溴苯腈辛酸酯。熔点43.3～43.9℃(文献值45～46℃），纯度96%，产率96.8%。据文献报道，反应还可在吡啶存在下，在二甲苯溶剂中进行（反应式略）。
乳油配制。将163.5g (0.406mol)溴苯腈辛酸酯、11.5g十二烷基苯磺酸钙、18.5g辛基酚聚氧乙烯（10）醚、300mL二甲苯混合搅拌至溶解，补加二甲苯至乳油体积达500mL，搅拌均匀。
