Non-symmetric, partially fluorinated lubricant additives

   
   

Novel non-symmetric, partially fluorinated compositions and method of manufacture which are useful as lubricants or as additives to lubricant formulations involving the molecular structure: R.sub.1f --F'--R.sub.2 --F"--R.sub.3h where R.sub.1f represents a wholly or partially fluorinated organic residue end group, F' and F" represent functional linkages which may be alike or different, R.sub.2 represents the backbone and R.sub.3h represents a non-fluorinated organic residue end group. Such compositions are produced by reacting a mixture of alcohols, mercaptans or amines containing at least one partially fluorinated compound and at least one non-fluorinated compound in the mixture, thus producing the R.sub.1f and the R.sub.3h residues, with a difunctional organic compound (e.g., diacid, dinitrile, disulfonyl halide, diisocyanate, diisothiocyanate, diphosphoryl halide or dithiophosphoryl halide).

Composições da novela e método non-symmetric, parcialmente fluorinated da manufatura que são úteis como lubrificantes ou como aditivos aos formulations do lubrificante que envolvem a estrutura molecular: R.sub.1f -- F' -- --F R.sub.2 "-- R.sub.3h onde R.sub.1f representa grupo orgânico completamente ou parcialmente fluorinated da extremidade do resíduo, F ' e F" representa os enlaces funcionais que podem ser semelhantes ou diferentes, R.sub.2 representa a espinha dorsal e R.sub.3h representa um grupo orgânico non-non-fluorinated da extremidade do resíduo. Tais composições são produzidas reagindo uma mistura dos álcoois, dos mercaptans ou dos amines contendo ao menos um composto parcialmente fluorinated e ao menos um composto non-non-fluorinated na mistura, assim produzindo o R.sub.1f e os resíduos de R.sub.3h, com um composto orgânico do difunctional (por exemplo, diacid, halide dinitrile, do disulfonyl, diisocyanate, diisothiocyanate, halide do diphosphoryl ou halide do dithiophosphoryl).
