| titleOfInvention | METHOD FOR PRODUCING PERFLUORNONANES |
| abstract | Perfluoro-nonanes are prepd. by reacting perfluoro-nonenes. (C9F18) in liq. phase with F2 at -40 to +120 degrees C. New prods. are (CF3)2CF 2CFCF2CF3 (I), (CF3CF2)2C(CF3)CF(CF3)2 (II) and CF3CF2CF2CF(CF3)CF2CF(CF3)2 (III). Cpds. (I) and (II) are pref. obtd. from (CF3)2CF 2C=CFCF3 and/or (CF3)2CF (CF3CF2)C=C(CF3)2. Cpd. (III) is pref. obtd. from CF3CF2CF2C(CF3)=CFCF(CF3)2 in cis and/or trans form. The reaction is pref. performed at +20 to +70 degrees C without a diluent. The prods. are useful as hydraulic fluids, dielectrics, propulsion agents for turbines, heat conductors and refrigerants in mechanical and electrical devices. They are also useful as inert solvents partic. in reactions involving F2. |
