摘要 |
NEW MATERIAL:The compound of formula I (R is hydrocarbon group; n is >=4). EXAMPLE:Pentadecalfluorothiol-octanoic acid myristyle ester. USE:A lubricant exhibiting excellent lubrication effect even at a low temperature. It has rustproofing activity by sulfur atom introduced into the molecule. Suitable for lubrication of particular materials especially magnetic recording medium carrying ferromagnetic metal thin film, etc. PREPARATION:The compound of formula I can be produced by reacting a perfluoroalkylcrboxylic acid chloride of formula II with nearly equimolar about of a mercaptan of formula R-SH in a solvent such as chloroform in the presence of a dehydrochlorination agent such as pyridine. |
