十一年前,维提格(Wittig)第一次合成了四苯硼酸盐。这个硼的有机络合物就陆续地被应用到分析化学中。到目前为止,各国化学家介绍这方面的文献巳超过500篇以上,研究結果表明,四苯硼酸盐能用于定量測定鋰、鈉、鉀、铷、(?)等碱金属元素以及铵、铊等。其中特别对于鉀的测定是十分成功的。从文献记载来看,四苯硼酸盐不仅适宜于經典的重量及容量分析方法,而且此种試剂在一些物理化学分析法中亦常被采用(例如比色、比浊测定和电位、电导、电流、高頻滴定等)。我国过去对这方面的工作研究得較少,但近年来我們顺利地合成了四苯硼酸鈉盐,为有助于应用四苯 Eleven years ago, Wittig first synthesized tetraphenylborate. The boron organic complex is gradually applied to analytical chemistry. So far, more than 500 articles have been introduced by chemists around the world. The results show that tetraphenylborate can be used for the quantitative determination of alkali metal elements such as lithium, sodium, potassium, rubidium, Thallium and so on. Among them, the determination of potassium is very successful. From the literature, tetraphenylborate is not only suitable for classical weight and volume analysis methods, but it is also commonly used in some physicochemical methods (such as colorimetric, turbidimetric and potentiometric, conductance , Current, high-frequency titration, etc.). In the past, China has studied less work in this area, but in recent years, we successfully synthesized tetraphenylborate sodium salt, which is helpful for the application of tetraphenylbenzene
