โœฆ Synopsis

The ether groups of ethylene oxide, and/or propylene oxide-fatty alcohol condensates were cleaved by reaction with 50% hydrobromic acid (in glacial acetic acid) in sealed Pyrex glass tubes. The resulting alkyl bromides were extracted with carbon disulphide and chromatographed on 5% OV-210 columns. Peak areas were used to determine the number of moles of alkylene oxide in the condensate. A series of ethylene oxide-fatty alcohol condensates were tested, and the results were in good agreement with those obtained from nuclear magnetic resonance methods, A further series of products consisting of mixed alkylene (ethylene and propylene) oxide-fatty alcohol condensates were also examined.

A convenient and reliable gas-liquid chromatographic method for determining the free fatty acids in biological specimens is described. The free fatty acids were extracted with hexane in the presence of H3PO4 and then back-extracted from the hexane phase into a very small volume of trimethyl (alpha,
