溴苯腈

溴苯腈用途

【用途一】
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。

The transformation of organic halogenated pesticides by laccase-mediator system has been investigated. Twelve pesticides were assayed in the presence of nine different mediators. Acetosyringone and sy...

Microbial degradation of the benzonitrile herbicides dichlobenil, bromoxynil and ioxynil in soil and subsurface environments--insights into degradation pathways, persistent metabolites and involved degrader organisms.

Environ. Pollut. 154(2) , 155-68, (2008)

The benzonitriles dichlobenil, bromoxynil and ioxynil are important broad-spectrum or selective herbicides used in agriculture, orchards and public areas worldwide. The dichlobenil metabolite 2,6-dich...

Analysis of trace levels of pesticides in rainwater by SPME and GC-tandem mass spectrometry after derivatisation with PFBBr.

Anal. Bioanal. Chem 387(1) , 359-68, (2007)

Solid-phase microextraction (SPME) was used for the analysis of some pesticides (bromoxynil, chlorotoluron, diuron, isoproturon, 2,4-MCPA, MCPP and 2,4-D) in rainwater after derivatisation with PFBBr ...
