This is evident from the Science Citation Index which lists The Determination of Ionization Constants by A. Albert and E. P. Serjeant (1971) as one of the most widely quoted books in the chemical literature. Although, ultimately, there is no satisfactory alternative to experimental measurement, it is not always convenient or practicable to make the necessary measure ments and calculations. Moreover, the massive pK. compilations currently available provide values for only a small fraction of known or possible acids or bases. For example, the compilations listed in Section 1. 3 give pK. data for some 6 000--8 000 acids, whereas if the conservative estimate is made that there are one hundred different substituent groups available to substitute in the benzene ring of benzoic acid, approximately five million tri-substituted benzoic acids are theoretically possible. Thus we have long felt that it is useful to consider methods by which a pK. value might be predicted as an interim value to within several tenths of a pH unit using arguments based on linear free energy relationships, by analog | 出版日期 | Book 1981 | 关键词 | amines; aromatic; carboxylic acid; energy; experiment; extraction; molecule; phenol; phenols; reactions; spect | 版次 | 1 | doi | https://doi.org/10.1007/978-94-009-5883-8 | isbn_softcover | 978-94-009-5885-2 | isbn_ebook | 978-94-009-5883-8 | copyright | D.
