title: [Optimating the availability of homologous quaternary ammonium compounds/3rd communication: The influence of salts on in vitro distribution of benzilic acid esters of homologous dimethyl-(2-hydroxyethyl)-alkyl-ammoniumbromides (author's transl)].
abstract: The addition of NaBr, Na-butansulfonate or Na-trichloracetat increases the partition coefficients of homologous quaternary cholinesters of benzilic acid between n-octanol and water. In a three-phase model (water/n-octanol/water) thus the rates of equilibration increase considerably for hydrophilic compounds.
