FLUORINE-CONTAINING COMPOUND AND PREPARATION THEREOF AND LUBRICANT COMPOSITION CONTAINING FLUORINE-CONTAINING COMPOUND AND MAGNETIC RECORDING MEDIUM |
摘要 |
NEW MATERIAL:A compound of formula I (Rf is 6-50C fluoroalkyl ether; R is aliphatic alkyl, aliphatic alkenyl). USE:The compound of formula I expresses a good lubricating performance due to the synergistic effects of the respective terminal groups under all environments including severe low humidity environments. The formation of a lubricant layer containing the compound on the metal thin film of a metal thin layer type magnetic recording medium directly or through a protecting layer permits to impart good durability to the recording medium. PREPARATION:A fluorine-containing alkylamide ester of formula II is reacted with the tetrahydrofuran solution of a borane tetrahydrofuran complex, followed by reducing the carbonyl group of the reaction product to provide the compound of formula I. |
