水杨酸络合物在分析上有用,对络合物形成的研究也有一定的意义,不过这一类络合物的络合反应还有一些问题未阐明,关于水杨酸铜络合物,文献上已有不少的报导,但意见不一致.A.K.Бабко根据Spacu等对晶体组成的研究结果,认为水溶液中只形成CuSal和CuSal_2~(2-)(H_2Sal代表水杨酸),并由光度法测得其逐级不稳定常数分别是10~(-6.3);Pecci等,Укше等对于该体系络合质点组成的看法与Бабко一致,他们测得的不稳定常数与Бабко的基本符合,只是由于Pecci用pH滴定法测得
Salicylic acid complex in the analysis of useful, complex formation of the study also has some significance, but this type of complex complexation reaction there are some problems not elucidated on the copper salicylate complexes, According to the study on the crystal composition of Spacu et al., It is considered that only CuSal and CuSal_2 ~ (2 -) (H 2 Sal for salicylic acid) are formed in the aqueous solution and are determined by photometry The step-by-step instability constants were measured respectively from 10 to (-6.3). Pecci et al., Укше, etc., agreed with Бабко for the composition of the complexed particles. The observed instability constants were basically consistent with Бабко, Pecci is measured by pH titration
