FLUORINE-CONTAINING COMPOUND, ITS PRODUCTION AND LUBRICANT COMPOSITION AND MAGNETIC RECORDING MEDIUM CONTAINING FLUORINE-CONTAINING COMPOUND

摘要

NEW MATERIAL:A fluorine-containing compound expressed by formula I (Rf is 6-50C fluoroalkyl ether terminal group; R1 is aliphatic alkyl terminal group or aliphatic alkenyl terminal group; R2 and R3 are aliphatic alkyl). EXAMPLE:A fluorine-containing compound expressed by formula II. USE:A lubricant for precise machines and parts requiring lubrication with a high accuracy, surfactants, mold release agents, rust inhibitors, etc., especially a lubricant for metallic thin-film type magnetic recording media capable of producing excellent lubricating performance in all environments including severe low-humidity environment and imparting excellent durable reliability to the metallic thin-film type magnetic recording media. PREPARATION:A fluorine-containing alkyl amide ester expressed by formula III is reacted with a solution of a borane tetrahydrofuran complex in tetrahydrofuran to reduce the carbonyl group. Thereby, the objective compound expressed by formula I is obtained.
