Studies of Acid-Base Equilibria in non-Aqueous Media

Описание:
Acids and bases are widely used among many chemists. The more it is known about the properties of acids and bases in certain solvent, the easier it is to choose the suitable compound for system under study. In this work, hundreds of pKa values of neutral and cationic acids have been presented in acetonitrile, tetrahydrofuran and 1,2-dichloroethane. Superbases are investigated in less acidic solvent– tetrahydrofuran, superacids are studied in 1,2- dichloroethane. In acetonitrile, two scales – acidity scale and basicity scale are composed to the full possible span. These two scales are irreplaceable tools for further acid-base studies. In this work many new types of compounds have been presented – superbasic guanidinophosphazenes, basic alkyl-substituted guanidines and highly sterically strained and often strong acidic properties having pentakis(trifluoromethyl)phenyl derivatives. pKa values of many of those compounds have been measured which shows us exactly the acidic-basic...Похожие книги
