SYNTHESIS OF NEW HIGHLY LYPOPHILIC ETHOXYLATED IONIC LIQUIDS AS PROMISING ACTIVE COMPONENTS FOR ION SELECTIVE ELECTRODES
Abstract
The convenient method for preparation of ethoxylated highly lipophilic quaternary ammonium salts has been developed, including alkylation of methyl gallate with dodecyl bromide, hydride reduction of ester group, introduction of the polyethoxylated fragment into the side chain, substitution of the terminal hydroxy group by chlorine and quaternization by a tertiary amine. The salts prepared possess the properties of ionic liquids and can be of interest as active components for ion selective electrode membranes.
