(57) [Abstract] (Modified) [Problem] A partially fluorinated alkyl compound, and excellent lubrication effect is maintained for a long time under various use conditions, and excellent running property, wear resistance, durability and the like are obtained. Provided is a lubricant for a magnetic recording medium. A partially fluorinated alkyl compound of the general formula 1. (R is a saturated aliphatic hydrocarbon group / unsaturated C6-30, Rf is a fluoroalkyl group of saturated / unsaturated, divalent hydrocarbon X 1 may be substituted with a hydroxyl / amino group Group, aromatic or heterocyclic group, or hydrocarbon group / X 2 and X 3 are the same or different from each other, and may be substituted with hydrogen or a hydroxyl / amino group in the aromatic or heterocyclic group substituted with an aromatic ring, or the hydrocarbon group substituted with an aromatic ring. A group or an aromatic ring group. ) For example C 18 H 37 -CH (COO ( CH 2) 3 N (C 2 H 5) 2) CH 2 COORf. |
