发明名称 Process for improving color and color stability of oleic aci d
摘要 The invention is a method for improving the color and color stability of oleic acid by a two column distillation process in which the oleic acid to be color improved is introduced into a first distillation zone containing an enriching section and a stripping section providing a minor amount of a topping product and a major amount of underflow containing the oleic acid and passing the oleic acid to a bottom portion of a second distillation zone having an enriching section to recover the improved oleic acid with improved color and color stability as a top product from the second distillation zone.
