Abstract

Uitravlolet absiorptlon and''C NMR spectroscopk technlques are used In conjunctlon wlth potentlometrlc studles to characterize the lnteractlon of carbonate Ions wlth trlluoroacetyl-p- butylbenzene, a solvent often utlllzed to prepare llquld/potymerlc membrane carbonate- selectlve electrodes. Single-phase spectroscopic experbnents In cyclohexane sug-ged that carbonate ions react with the carbonyl carbon atom of the fhroroketone to form IlpophUlc ...
