Technical Abstract: Linoleic acid is the major component of soybean, corn, sunflower, and other commodity oils. This makes methyl linoleate a better model than methyl oleate as a compound for investigating the chemical modification of vegetable oils for industrial purposes. In the current work, we report the reaction of the radical addition of dialkyl (methyl, ethyl, n-butyl) phosphites to the double bonds in methyl linoleate. The high temperature needed for some of the radical initiators caused a transesterification between the ester groups. An optimization of the conditions (temperature, initiator, etc.) was done. The MS spectra of the products is reported.
