This second report describes the characterization of C 18 aromatic esters from the heated linoleate and the independent synthesis of two of them. The esters were isolated by a combination of molecular distillation, urea adduction, column chromatography, and gas chromatography. They were characterized by infrared, ultraviolet, NMR, and mass spectroscopy. The analytical data for the isolated esters were compared with the data for the synthetic esters, methyl 11‐(2′‐methylphenyl) undecanoate, methyl 7‐(2′‐pentylphenyl) heptanoate, and methyl 8‐(2′‐butylphenyl) octanoate. The latter two compounds were found to be components of the aromatic fraction isolated from heated linoleate, and their synthesis is deseribed in detail.
