Dimers were isolated from two samples of partially hydrogenated soybean oil which had been used for frying. They were then separated into their component structures using an LC-18 octadecyl bonded, HPLC column with acetone-acetonitrile (1:1, v/v) as

Methods for separation of various structural entities of dimers from heated fats and oils are not yet available. A series of dimers, representative of these, which may be formed in thermal oxidative reactions of fats and oils have recently been made

Dimers, structurally representative of those formed during thermal-oxidative reactions in fats and oils, including the dihydroxy, tetrahydroxy, and the diketo dimer of methyl stearate, were synthesized to be used as standards and model compounds for

A high performance size exclusion Chromatographic method was developed for the separation of monomer, dimer and trimer fatty acids in thermally oxidized or used fats and oils. The system was composed of two styrene/divinylbenzene copolymer columns wi
