摘要
采用毛细管电泳法测定精对苯二酸生产过程母液中的主要有机付产物,试验并找到了测定这些有机杂质的最佳操作条件,以便更好地控制母液回流比。
Seven by-products in the mother liquor from the refining process of p-phthalic acid were separated and determined by the capillary electrophoretic method in an electrolytic solution of borax and cyclodextrin with the working voltage at +24kV and the temperature of the separation chamber at 30℃. The time taken for the sampling by gravity is 10s. The optimum conditions for the determination of the seven by-products and for the control of re-cycling ratio of the mother liquor were found.
