Physicochemical characterization of new sulfonate and sulfate ammonium ionic liquids

In this work we describe the synthesis and thermal properties of nine new salts derived from ammonium that incorporate alkanesulfonate and alkanesulfate anions. Their structures were confirmed by 1H and 13C NMR and HRMS-ESI. Their thermal properties were determined by differential scanning calorimetry (DSC). Three of the synthesized salts have been shown to be room temperature ionic liquids: N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium butanesulfonate, N-ethyl-N,N-dimethylbutylammonium ethylsulfate, and N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium ethylsulfate. Experimental densities, speeds of sound, dynamic viscosities, and refractive indices of these three ionic liquids were measured at T = 298.15 K.

Process for preparation of oxyglutaric acid ester derivatives

A process for preparing an oxyglutaric acid ester derivative of the formula: STR1 in which each of R1 and R2 is C1-5 alkoxy, C1-7 aralkyloxy, C7-9 halogenated aralkyloxy or phenyl, R4 is a hydroxyl-protecting group, and R5 is C1-10 alkyl which may have a substituent, comprises the steps of reacting a methyl phosphonate derivative or methyl phosphine oxide derivative with an oxyglutaric acid mono-ester to give a reaction product which comprises an oxyglutaric acid derivative having a phosphorus-containing group and a pentenedioic acid mono-ester (by-product), removing the pendenedioic acid mono-ester from the reaction product to isolate the oxyglutaric acid derivative, and converting the isolated oxyglutaric acid derivative into the oxyglutaric acid ester derivative. A process for obtaining an optically active oxyglutaric acid ester derivative is also disclosed.
