Fluorination process of halogenated organic compounds |
摘要 |
<p>Fluorination process of halogenated organic compounds with gaseous anhydrous HF characterized in that a catalyst comprising a supported Cr(III) amorphous compound is used, wherein the support consists in an aluminum trifluoride (AlF3) having an high surface area and an high pore volume obtainable by fluorination with gaseous HF of alumina having surface area of at least 150 m<2>/g and pore volume not lower than 0.3 cc/g and wherein said alumina comprises from 0.5 up to 15% by weight of silicon oxide, the chromium amount being comprised between 1 and 20% by weight.</p> |
