Abstract
Process for reducing the organic chlorine content in oils and fats of the UCO, AVR and PO classes by means of heat elimination reactions with a reagent selected from : alkali metal carbonates and alkali-earth metal carbonates; alkali metal alcoholates and alkali-earth metal alcoholates; finely divided elementary metals of the third and fourth period of the Periodic Table of Elements; and mixtures thereof. The reaction products are then mixed with wash water added with citric or formic acid, to favour the trans fer of said inorganic salts from the oily phase to the aqueous phase. Finally, such mixture is centrifuged to separate a ready-to-use oily phase with reduced content of organic chlorine, and an aqueous phase containing in solution inorganic salts of chlorine, for further purification.
