Summary Safflower oil was heat‐bodied at 300°C., and its methyl esters were fractionated by vacuum‐distillation and with urea. A monomeric cyclic compound was isolated as the non‐adduct‐forming distillate. It was presumably a cyclized product of methyl linoleate as it has a mean molecular weight of 293.7 (theo. 295) and a mean unsaturation of approximately one double bond per mole of methyl ester corresponding to a hydrogen deficiency of 1.96 to 2.01.
