Publikováno v: European Journal of Lipid Science and Technology, 114(1), 31-48. Wiley-Blackwell
An experimental study to modify Sterculia foetida L. oil (STO) or the corresponding methyl esters (STO FAME) to branched ester derivatives is reported. The transformations involve conversion of the cyclopropene rings in the fatty acid chains of STO t
