2-硝基-4-甲磺酰基苯甲酸是一种重要的化学原料,是合成甲基磺草酮的一个重要中间体。甲基磺草酮是Zeneca农化公司开发的三酮类除草剂,是一种玉米田专用除草剂,它以杀草谱广、活性高、可混性强、毒性低、对环境友好、对后茬作物安全、使用灵活等特点在国外已取得相当大的成功,而国内的合成工艺仍不成熟,因此对2-硝基-4-甲磺酰基苯甲酸合成工艺进行研究具有广阔的应用前景。 2-Nitro-4-methylsulfonylbenzoic acid is an important chemical raw material and an important intermediate for the synthesis of mesotrione. Mesotrione is a triketone herbicide developed by Zeneca Agrochemicals and is a corn herbicide. It is widely used in the field of herbicide and has the advantages of broad spectrum herbicide, high activity, strong compatibility, low toxicity and environment friendliness. The crop success and flexibility have achieved considerable success abroad, but the domestic synthesis process is still not mature, so the research on the synthesis of 2-nitro-4-methanesulfonylbenzoic acid has a bright future. .
