trans ‐3,5‐Dimethoxystilbene has been isolated from high quality tall oil fatty acids (unsaponifiables 1.5% maximum, rosin acids 1.5% maximum), using liquid column chromatography and low temperature solvent fractional crystallization. The structure of this compound was determined with the aid of IR, mass and NMR spectrometry. The trans ‐3,5‐dimethyoxystilbene was found to be responsible for the development of a red color during the epoxidation of the tall oil fatty acids.
