酰化反应生成2,4-二氯-3-硝基-5-氟苯甲酰氯的含量计算方法
摘要：
本发明公开了一种酰化反应生成2,4-二氯-3-硝基-5-氟苯甲酰氯的含量计算方法，包括空白校正步骤、样品测定步骤和计算步骤，2,4-二氯-3-硝基-5-氟苯甲酰氯可以通过与水彻底反应生2,4-二氯-3-硝基-5-氟苯甲酸和HCl，与甲醇彻底反应生成2,4-二氯-3-硝基-5-氟苯甲酸甲酯和HCl，通过这两个反应生成的酸的量，来计算2,4-二氯-3-硝基-5-氟苯甲酰氯的具体含量。本发明的这种酰化反应生成2,4-二氯-3-硝基-5-氟苯甲酰氯的含量计算方法，没有必要考虑水分是否对产品有没有影响，操作方便可行，省时省力，含量计算准确性高。
摘要（英）：

The invention discloses a content calculation method of 2,4-dichloro-3-nitro-5-fluorobenzoyl chloride generated by acylation reaction. The content calculation method comprises a blank correction step, a sample measurement step and a calculation step. 2,4-dichloro-3-nitro-5-fluorobenzoyl chloride can completely react with water to produce 2,4-dichloro-3-nitro-5-fluorobenzoic acid and HCl, and can completely react with methanol to produce 2,4-dichloro-3-nitro-5-methyl fluorobenzoate and HCl, and the specific content of 2,4-dichloro-3-nitro-5-fluorobenzoyl chloride can be calculated according to the quantity of acid produced by the two reactions. The content calculation method of 2,4-dichloro-3-nitro-5-fluorobenzoyl chloride generated by acylation reaction disclosed by the invention does not need to consider whether products can be influenced by moisture or not, is convenient and feasible to operate, ensures that both the time and labor can be saved, and is high in content calculation accuracy.
