Abstract

In aqueous solutions (with or without salts) containing carboxylic acids, water can be bound with anhydrous sodium sulphate at a molar ratio of [Na2SO4]/[H2O] ≥ 0.9. This is used prior to gas chromatography of aliphatic and aromatic di- and poly-carboxylic acids (oxalic to mellitic acid) in aqueous matrices (solutions, suspensions). Such acids are extracted quantitatively into diethyl ether within 8-10 min, which is much faster than conventional methods. Esterification is done with diazomethane.
