Summary A procedure for the chromatographic separation and determination of the ester mixtures of glycerin, ethylene glycol, and polyethylene glycol is presented. The adsorbent is silea gel, and the mobile phase is a series of solvents with increasing polarity. A procedure for quantitative determination of small amounts of monoglyceride present in a glyceryl ester mixture is presented. A solvent system different from that used for glyceryl and ethylene glycol ester mixtures was developed for ester mixtures of polyethylene glycols. The esters of polyethylene glycols with average molecular weights of 300–600 were shown to give the same chromatogram.
