PROCESS FOR IMPROVING COLOR AND COLOR STABILITY OF OLEIC ACID |
摘要 |
The invention is a method for improving the color and color stability of oleic acid by a two column distillation process. The oleic acid to be color improved is introduced into a first distillation zone (1) containing an enriching section (2) and a stripping section (3) providing a minor amount of a topping product and a major amount of underflow containing the oleic acid. Passing the oleic acid to a bottom portion of a second distillation (24) zone having an enriching section (25) to recover the improved oleic acid with improved color and color stability as a top product from the second distillation zone.
