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 aluminium 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.

Process for the preparation of a composition comprising long chain polyunsaturated fatty acids of the ω-3 and/or ω-6 series and/or the pharmaceutically and/or dietetically acceptable C1-C3 alkyl esters and/or the salts thereof with an inorganic or organic base with an assay higher than 50% by weight, wherein the said polyunsaturated compounds are first concentrated up to a gas chromatographic purity corresponding to the assay required for the final composition and then dissolved in aprotic and/or apolar and/or slightly polar solvents before being purified by contact with silicon derivatives.
