Mannich base composition and lubricating oil compositions containing same |
摘要 |
New Mannich bases and the alkaline earth metal salts thereof are prepared by condensing formaldehyde and a polyamine with a sulfur-containing phenolic mixture consisting of (1) from 5 to 40% of a sulfurized alkylphenol of the formula <IMAGE> wherein R is C8-C36 alkyl, n is an integer from 1 to 8, and y is an integer from 1 to 9, and (2) from 95 to 60% of a phenolic mixture consisting of (a) from 95 to 30% phenol alkylated with a propylene tetramer and (b) from 5 to 70% phenol alkylated with a straight-chain alpha-olefin of from 16 to about 28 carbon atoms or alpha-olefin mixtures wherein the alpha-olefins are of from 16 to about 28 carbon atoms. They are useful as additives for lubricating oils, particularly for use in marine cylinder lubricating oils.
