“…Most likely, methyl isobutyl ketone is the best known example, since five acids (perchloric, hydrochloric, salicylic, and acetic acid as well as phenol) can be titrated in it with TBAH titrant, using potentiometric end point determination (26). The elegant solution is overshadowed by the mercury pollution of the environment.…”

“…Figure 3.7 shows the titration curve for a mixture of several acids in 4-methyl-2-pentanone (MIBK). In the figure, HClO 4 and HCl, which are strong acids in water, are differentiated, and phenol, which is a very weak acid, can accurately be determined [21]. Acid-base titrations in nonaqueous solvents have wide applicability [1,3,22].…”

This chapter discusses acid-base reactions in nonaqueous solvents, with particular emphasis on how they differ from those in aqueous solutions. The problem of pH in nonaqueous solutions is also discussed. The Brønsted acid-base concept that an acid is a proton donor and a base is a proton acceptor is adopted. The relation between an acid A and its conjugate base B is expressed byThe reaction between an acid A 1 and a base B 2 is a proton transfer from A 1 to B 2 , A 1 becoming its conjugate base B 1 and B 2 its conjugate acid A 2 :

“…Saturated NaClO 4 in 2-propanol was used as the electrolyte. The DNAPL was diluted in methyl isobutyl ketone (MIBK) (98.5%, Fisher Scientific Co), which is known to be a versatile solvent [Bruss and Wyld, 1957]. The titrant used was tetrabutylammonium hydroxide (Fisher Scientific Co).…”
