In the present paper, citric acid, acetic anhydride, polyethyleneoxide nonyl phenyl ether and diethanolamine were used as raw materials. The raw materials were purified, and the intermediate products were synthesized. Finally, the citric acid mono polyethyleneoxide nonyl phenyl ether amber diehylene glycol dinitrate diglycollic amide was made. The acidamide of the product synthesized was determined by IR. There is a characteristic peak of C=O in acidamide at 1 642.39 cm(-1). Using potassium rhodanate as a internal standard, and according to Lambert-Beer law, a method to determine the citric acid mono polyethyleneoxide nonyl phenyl ether amber diehylene glycol dinitrate diglycollic amide was developed. The linear regression equation is A = 0.007 6m+0.325 6 with a correlation coefficient (r2) of 0.998 9. The experimental results of the precisions and recoveries are satisfied. The method is very necessary for confirming the reaction extent and controlling quality of citric acid mono polyethyleneoxide nonyl phenyl ether amber diehylene glycol dinitrate diglycollic amide. So, the synthesis process conditions were right according to the IR data.
本文以柠檬酸、乙酸酐、聚氧化乙烯壬基苯基醚和二乙醇胺为原料。对原料进行提纯，合成中间产物。最终制得柠檬酸单聚氧化乙烯壬基苯基醚琥珀酸二甘醇二硝酸酯二甘醇酰胺。采用红外光谱法对合成产物的酰胺进行测定。酰胺中C=O的特征峰位于1642.39 cm(-1)处。以硫氰酸钾为内标，根据朗伯-比尔定律，建立了一种测定柠檬酸单聚氧化乙烯壬基苯基醚琥珀酸二甘醇二硝酸酯二甘醇酰胺的方法。线性回归方程为A = 0.007 6m + 0.325 6，相关系数（r2）为0.998 9。精密度和回收率的实验结果令人满意。该方法对于确定柠檬酸单聚氧化乙烯壬基苯基醚琥珀酸二甘醇二硝酸酯二甘醇酰胺的反应程度和控制其质量非常必要。因此，根据红外光谱数据可知合成工艺条件是正确的。
