    Solvation dynamics of lithium salts in wet nitrobenzene

  • Original language description

    Dynamics of solvation of lithium salts in "wet" nitrobenzene was studied by 7Li NMR and by FTIR. Well-resolved NMR peaks corresponding to various solvatomers of Li have been observed in solution of LiClO4 in nitrobenzene saturated with water. It has beenfound that the solvation equilibria are dominated by slow kinetics involving mixed solvatomer Li(nitrobenzene/water). At the glass wall this solvatomer decomposes slowly, over period of many hours, to fully hydrated Li(water) solvatomer. On the other hand, no such decomposition is observed at the Teflon/nitrobenzene interface and the Li(nitrobenzene/water) even more slowly converts to solvatomer Li(nitrobenzene), solvated mostly by nitrobenzene. The effect of the anion on the "free" OH stretch at 3583and 3672 cm-1, respectively, has been studied by the FTIR.

    Dynamika solvatace litné soli v "mokrém" nitrobenzenu

  • Czech description

    Metodami 7Li NMR a FTIR byla studována dynamika solvatace litné soli v "mokrém" nitrobenzenu. V roztoku LiClO4 v nitrobenzenu saturovaném vodou byly pozorovány dobře rozlišené píky NMR příslušející různým solvatomerům Li. Bylo zjištěno, že řídícím dějemsolvatační rovnováhy je pomalý proces zahrnující směsný solvatomer Li(nitrobenzen/voda). Tento solvatomer se na povrchu skla pomalu rozkládá (řadu hodin) na zcela hydratovaný solvatomer Li(voda). Nahražením skla teflonem se rozklad směsného solvatomeru ještě více zpomalí a výsledný produkt odpovídá solvatomeru Li(nitrobenzen), převážně solvatovanému nitrobenzenem. Vliv aniontu Li sole na signál "volného" OH u 3583 a 3672 cm-1 byl studován pomocí FTIR.
