2,2,2-TRIS-([1′,1′,1′,2′,2′,3′,5′,6′,6′,8′-UNDECAFLUORINE-5′,8′-DI-(TRIFLUOROMETHYL)- 4′,7′-DIOXY-9′-METHYLENEOXY CARBONYL) ETHANOL, AND PROCESS FOR PREPARATION THEREOF Russian patent published in 1997 - IPC

FIELD: chemical industry. SUBSTANCE: 2,2,2-tris-([1′,1′,1′,2′,2′,3′,5′,6′,6′,8′-undceaphtor-5′,8′-di- (trifluoromethyl)-4′,7′-dioxy-9′-(methylenenoxy carbonyl)ethanol is claimed as surfactant for treating metal and plastic surfaces, and antifriction lubricating material is prepared by reacting hexafluoropropylene and pentaerythrite oxide trimer fluorineanhydride in the presence of solvent and catalyst. EFFECT: more efficient preparation process. 5 cl, 1 tbl
