摘要： A method to refine a lubricant on a magnetic recording medium includes a compound A including a perfluoropolyether molecular structure having two hydroxyl groups at each of two ends and a compound B including the perfluoropolyether molecular structure having one hydroxyl group at each of two ends. The method includes putting the lubricant into a pressure vessel set at a pressure and a temperature and removing the compound B dissolved in an extracting medium of a supercritical carbon dioxide fluid that flows at a predetermined rate through the pressure vessel held at a predetermined temperature and at a predetermined pressure. The method performs recovering the compound A dissolved in the extracting medium that flows through the pressure vessel held at the predetermined pressure and at a temperature lower than the predetermined temperature or at the predetermined temperature and at a pressure higher than the predetermined pressure.

摘要： A method refines a lubricant comprising a compound having a perfluoropolyether structure via supercritical extraction. A lubricant is refined using the method and a magnetic recording medium that utilizes the refined lubricant. The refined lubricant exhibits excellent lubrication performance and long term stability in the magnetic recording medium. In one embodiment of the supercritical extraction, the lubricant contacts an extracting medium of supercritical carbon dioxide under a predetermined condition in a pressure vessel to remove ionic impurities and perfluoropolyether compounds having a weak polarity terminal group contained in the lubricant.
