โฆ Synopsis
With dimethyldisulfide the methylthio-derivatives of unsaturated fatty acid methyleaters are readily formed within 30 rnin at 70ยฐC.
Whereas the analysis of oleic and petroselinic acid methyl esters by gas liquid chromatography is very time consuming (separation time: 1 hour), their corresponding methylthio-derivatives can be quantitativclv determinated within 14 min.
