Knyazev, V. N.; Drozdov, V. A. published the artcile< Use of new titrants for conducting redox reactions in nonaqueous media>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is titrant redox nonaqueous potentiometry; borohydride titrant nonaqueous potentiometry; aminoethylhydroquinone titrant nonaqueous potentiometry; hydroquinone aminoethyl titrant nonaqueous potentiometry; chlorooxochromium titrant nonaqueous potentiometry; chromyl chloride titrant nonaqueous potentiometry; chlorooxochromate potassium titrant nonaqueous potentiometry; pyridine bromide perbromide redox titrant; selenium titration nonaqueous potentiometric.
NaBH4, 2,5-bis(diethylaminomethyl)hydroquinone, CrO2Cl2, CrO2(OK)Cl, and C5H5N.HBr3 were examined as titrants in nonaqueous media for Ag and UO22+ nitrates, Ti(IV), Hg(II), and Sn(II,IV) chlorides, H2SeO3, I, o- and p-benzoquinones, hydroquinone, resorcinol, pyrocatechol, alcs., aldehydes, etc. The titrations at 20±0.2.degree. were performed by using a potentiometer with different electrode pairs. With NaBH4 and a calomel – Pt electrode pair, individual compounds can be determined and Ag+ and Hg2+ salts can be differentially titrated in pyridine medium. The titrations with Mannich base were carried out in EtOH or MeOH; calomel – Pt and Pt- Sb electrode pairs were suitable for the titrations The reactions with Ag, Cu(II), and Hg(II) salts were quant. The Ag(I), Cu(II), and Hg(II) salts were reduced to Ag0, Cu(I), Hg(I). The mixtures of Ag+ + Hg2+ and Ag+ + Cu2+ can be titrated quant. PhOH, cresols, xylenols, guaiacol, hydroxybenzoic acids, styrene, aryl-α-tetralol, cyclohexene, diphenylpropane, 4-hydroxydiphenyl, and a number of other di- and trihydric phenols as well as their derivatives reacted quant. with C5H5N.HBr3 in an alk. medium (NaOAc), whereas α,β-nonsatd. acids did not.
