WebNotes on NMR Solvents. I. Introduction. Most NMR spectra are recorded for compounds dissolved in a solvent. Therefore, signals will be observed for the solvent and this must be accounted for in solving spectral problems. To avoid spectra dominated by the solvent signal, most 1 H NMR spectra are recorded in a deuterated solvent. WebToluene, xylene or chloroform improve the solubility of aromatic compounds. Recommended methods are both the volumetric titration with one or two component reagents, as well as the coulometric analysis. The latter is predominantly applied for low water concentrations (< 0.1 %). If chlorinated hydrocarbons contain free chlorine it is …
