METHOD OF PREPARING OF ADDITIVE AGENT TO POLYORGANOSILOXANES Russian patent published in 1995 - IPC

Abstract RU 2034868 C1

FIELD: lubricating oil production. SUBSTANCE: method involves interaction of oligoorganosiloxane of the general formula (CH3)3SiO[(CH3)2SiO]m-[(CH3)(CH2CH2CF3)SiO]nSi(CH3)3 where m = 5-63; n = 0-4 with cerium acetylacetonate at 240-290 C and transient metal organic compound (0.2-0.4 mas. p. per 100 mas. p. oligoorganosiloxane) taken from the group involving iron, nickel, cobalt, chrome and copper. Air is passed through the reaction mass following by interaction of bimetal products at 60-300 C. EFFECT: improved method of preparing. 1 tbl
