Указанные вещества используются в качестве нейтральных переносчиков (НП) в мембранах ионоселективных электродов, обратимых к двухзарядным неорганическим анионам. Проведено систематическое исследование гидратации ТФАФ и ряда его производных. ТФАФ обладает повышенной растворимостью в воде (коэффициент распределения D равен 415) по сравнению с п-МТФАФ, ДМТФАФ, ТМТФАФ и ГЭ п-ТФАБК (D в пределах 1360–2700), что не позволяет рекомендовать его в качестве НП для изготовления мембран электродов. Наиболее сильно гидратация протекает для ГЭ п-ТФАБК в щелочной среде. Установлено, что п-МТФАФ и ГЭ п-ТФАБК образуют кристаллические гидраты. Определены коэффициенты селективности карбонат- и сульфат-селективных электродов для всех изученных НП и составлен их ряд по улучшению селективности электродов: ТФАФ k п-МТФАФ k ДМТФАФ k ТМТФАФ k п-БТФАФ k ГЭ п-ТФАФ.</p></abstract><trans-abstract xml:lang="en"><p>UV-spectrophotometric and chromatographic studies of the distribution of trifluoroacetophenone (TFAF) and a number of its derivatives (heptyl ether of p-trifluoroacetylbenzoic acid (HE p-TFABA), p-methyltrifluoroacetophenone (p-MTFAF), 2,4-dimethyltrifluoroacetophenone (DMTFAF), 2,4,6-trimethyltrifluoroacetophenone (TMTFAF)) in a hexane-water system, which simplifies the modeling of a polyvinyl chloride membrane carbonate and sulfate-selective electrodes, were performed. These substances are used as neutral carriers (NC) in membranes of ion-selective electrodes, reversible to double-charged inorganic anions. A systematic study of the hydration of TFAF and a number of its derivatives was carried out. TFAF has increased solubility in water (the distribution coefficient D is 415) as compared to p-MTFAF, DMTFAF, TMTFAF and HE p-TFABA (D within 1360–2700), which does not allow to recommend it as an NC for making electrode membranes. The strongest hydration occurs for the HE p-TFABA in the alkaline medium. It has been found that p-MTFAF and HE p-TFABA form crystalline hydrates. The selectivity coefficients of carbonate and sulfate-selective electrodes were determined for all the NC studied and a number of them were made to improve the selectivity of the electrodes: TFAF k p-MTFAF k DMTFAF k TMTFAF k p-BTFAF (p-buthyltrifluoroacetophenone) k HE p-TFABA.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трифторацетофенон</kwd><kwd>гептиловый эфир п-трифторацетилбензойной кислоты</kwd><kwd>п-метилтрифторацетофенон</kwd><kwd>2</kwd><kwd>4-диметилтрифторацетофенон</kwd><kwd>2</kwd><kwd>4</kwd><kwd>6-триметилтрифторацетофенон</kwd><kwd>п-бутилтрифторацетофенон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>trifluoroacetophenone</kwd><kwd>p-trifluoroacetylbenzoic acid heptyl ether</kwd><kwd>p-methyltrifluoroacetophenone</kwd><kwd>2</kwd><kwd>4-dimethyltrifluoroacetophenone</kwd><kwd>2</kwd><kwd>4</kwd><kwd>6-trimethyltrifluoroacetophenone</kwd><kwd>p-butyltrifluoroacetophenone</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Молибдат-селективный электрод на основе высших четвертичных аммониевых солей / Е.М.
