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:
R1f—F′—R2—F″—R3h
where R1f represents a wholly or partially fluorinated organic residue end group, F′ and F″ represent functional linkages which may be alike or different, R2 represents the backbone and R3h 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 R1f and the R3h residues, with a difunctional organic compound (e.g., diacid, dinitrile, disulfonyl halide, diisocyanate, diisothiocyanate, diphosphoryl halide or dithiophosphoryl halide).
一种新型的非对称、部分氟化组合物及其制造方法,可用作润滑剂或作为润滑剂配方的添加剂,其涉及分子结构:R1f—F′—R2—F″—R3h,其中R1f代表全氟或部分氟化有机残基末端基团,F′和F″代表可能相同或不同的功能性连接,R2代表骨架,R3h代表非氟化有机残基末端基团。这种组合物是通过反应含有至少一种部分氟化化合物和至少一种非氟化化合物的醇、巯基或胺的混合物来制备的,从而产生R1f和R3h残基,与双官能有机化合物(例如二酸、二腈、二磺酰卤、二异氰酸酯、二异硫氰酸酯、二磷酰卤或二硫代磷酰卤)反应。
