ABSTRACT:
The present invention relates to a process for the preparation of a composition comprising unsaturated compounds, in particular polyunsaturated compounds, which comprises concentrating and purifying the compounds by contact with silicon and/or aluminum derivatives. The process of the invention represents an advantageous substitute of the usual distillation processes, coupled or not to chromatographic processes, and allows to isolate and remove polar byproducts.
