sodium potassium carbonate

Examples are sodium carbonate and potassium acid phthalate which are to standardize acid and base solutions.

例如碳酸钠和邻苯二酸氢钾,分别用来标定酸和碱溶液.

The results are summarized as follows: 1. The effect of four kinds of promoters ( potassium carbonate, EDTA, potassium sodium tartrate tetrahydrate, succinic acid) were investigated, further discussion about the activate species and the principles of selecting promoters were carried on.

结果如下：1.研究了四种助剂（碳酸钾，EDTA，酒石酸钾钠，丁二酸）对甲醇气相氧化羰基化催化剂性能的影响，并对催化剂活性物种的类型和助剂选择方法进行了探讨。
