本论文以邻氨基苯甲酸为原料,经由中间产物2-甲基喹唑啉酮化合物氧化合成了喹唑啉-4-酮-2-甲酸,产品采用IR对结构进行了表征。并对中间体和目标化合物的合成方法进行了合成条件筛选。优化反应条件为:回流温度在酸性条件下保持在70℃,反应8h,得2-羧基取代喹唑啉-4-酮的产率达54%,回流温度在碱性条件保持在80℃反应12,得2-羧基取代喹唑啉-4-酮的产率达45.9%。回流温度在中性条件保持在60℃,得2-羧基取代喹唑啉-4-酮的产率达45%

In this paper, to o-aminobenzoic acid as raw material, through the intermediate product 2 - methyl-quinazoline oxide ketone compounds synthesized quinazoline -4 - keto -2 - carboxylic acid, the product using IR characterization of the structure. Intermediates and target compounds and the synthesis method of filter synthesis conditions. Optimum reaction conditions are as follows: reflux temperature under acidic conditions maintained at 70 ℃, reaction 8h, a 2 - to replace the carboxyl quinazoline -4 - one of the production rate of 54 percent, the return temperature in alkaline conditions maintained at 80 ℃ reaction 12 , a 2 - to replace the carboxyl quinazoline -4 - one of the production rate of 45.9 percent. Return to neutral temperature conditions maintained at 60 ℃,
A 2 - to replace the carboxyl quinazoline -4 - one of the production rate of 45%
谁能帮我修改一下
