粗喹啉生产中游离酸分析方法的改进

Improvement of analytical method for free acid in crude quinoline production

粗喹啉提取工艺中,酸洗效果直接影响产品的收率和质量。硫酸喹啉盐分析中游离酸测定方法的干扰因素较多,对原方法改进后实验分析更加稳定,洗涤效率及产品产量得以提高。

For extraction of crude quinoline process, the effect of pickling directly affects the yield and quality of the product. In the analysis of quinoline sulfate,there are many interference factors in determination of free acid. The experimental analysis is more stable. Washing efficiency and product yield are improved after improvement of the original method.
