    • The invention pertains to a process for the purification of a polyol (per)fluoropolyether derivative [polyol (P)], said polyol (P) comprising one or more hydroxyl (per)fluoropolyether derivatives [PFPE (OH)] comprising at least one (per)fluoropolyoxyalkylene chain (chain R f ) and at least one end-group having formula -CF 2 CH 2 OCH 2 CH(OH)CH 2 OCH 2 CH(OH)CH 2 OH (t3), from a mixture of hydroxyl (per)fluoropolyether derivatives [mixture (M)], said mixture (M) comprising said polyol (P) and at least one hydroxyl (per)fluoropolyether derivative [PFPE (OH)] different from polyol (P) and comprising at least one (per)fluoropolyoxyalkylene chain (chain Rf) and at least one end-group selected from those having formulae -CF 2 CH 2 OH (t 1 ) and -CF 2 CH 2 OCH 2 CH(OH)CH 2 OH (t 2 ), said process comprising the following steps: step 1 : reacting the mixture (M) with a ketone and/or an aldehyde so as to yield corresponding mixture of cyclic ketal/acetal (per)fluoropolyether derivatives [PFPEs (OH) p ] [protected mixture (P)]; step 2: molecular distillation of the protected mixture (P) so as to isolate a protected product heavy residue [product (P r )]; step 3: hydrolyzing the product (P r ) so as to yield a deprotected product [product (P d )]; step 4: distillation under reduced pressure of the product (P d ) so as to obtain polyol (P).
    • 本发明涉及纯化多元醇(全)氟聚醚衍生物[多元醇(P)]的方法,所述多元醇(P)包含一种或多种羟基(全)含氟聚醚衍生物[PFPE(OH)],其包含至少一种( (OH)CH 2 OH(t3)的至少一个末端基团,由羟基(全)氟代聚醚衍生物[混合物(M)]的混合物,所述混合物 (P)和至少一种不同于多元醇(P)的羟基(全)氟聚醚衍生物[PFPE(OH)]并且包含至少一个(全)氟聚氧化烯链(链Rf)和至少一个末端 - 基团选自具有式-CF 2 CH 2 OH(t 1)和-CF 2 CH 2 OCH 2 CH(OH)CH 2 OH(t 2)的那些,所述方法包括以下步骤:步骤1:使混合物(M)与酮和/或醛反应, 产生相应的环缩酮/缩醛(全)氟聚醚衍生物[PFPE(OH)p] [保护的混合物(P) ]。 步骤2:保护的混合物(P)的分子蒸馏,以分离受保护的产物重残渣[产物(Pr)]; 步骤3:水解产物(Pr)以产生脱保护的产物[产物(Pd)]; 步骤4:在减压下蒸馏产物(Pd),得到多元醇(P)。

    • The present invention relates to a phosphazene compound [compound (L)] comprising a cyclophosphazene central core wherein each phosphorus atom of said core bears a substituent independently selected from: a) a chain (A), said chain (A) comprising a (per)fluoropolyether chain [chain (R f )], one or more aromatic or heteroaromatic moieties [moiety/ies (Ar m )] and, optionally, one or more hydroxy groups and b) a chain (B), said chain (B) comprising a (per)fluoropolyether chain [chain (R f )] and one or more hydroxy groups with the proviso that at least one phosphorous atom of the central core is substituted with chain (A) and to mixtures of compounds (L). The invention further relates to methods for preparing compounds (L), to lubricant compositions comprising compounds (L) and to methods for lubricating magnetic recording media comprising applying a compound (L) or a lubricant compositions containing them to the surface of said medium.
    • 本发明涉及包含环磷腈中心核心的磷腈化合物[化合物(L)],其中所述核心的每个磷原子具有独立地选自以下的取代基:a)链(A),所述链(A)包含(每个 )氟聚醚链[链(Rf)],一个或多个芳族或杂芳族部分[部分(Arm)]和任选的一个或多个羟基和b)链(B),所述链(B)包含 (全)氟聚醚链[链(Rf)]和一个或多个羟基,条件是中心核心的至少一个磷原子被链(A)和化合物(L)的混合物取代。 本发明还涉及制备化合物(L),包含化合物(L)的润滑剂组合物的方法和用于润滑磁性记录介质的方法,包括将含有它们的化合物(L)或润滑剂组合物施加到所述介质的表面。
