ABSTRACT:
Distilled tall oil fatty acids are improved by irradiation which isomerizes trans-dimethoxystilbene (trans-DMS) impurity to cis-dimethoxystilbene which is easily removed by fractional distillation. Thus, the trans-DMS is removed without loss of fatty acid components from the distilled tall oil fatty acid.
