Abstract

1358961 Lubricant antioxidants BRITISH PETROLEUM CO Ltd 1 Feb 1973 [15 Feb 1972] 6896/72 Heading C5F An antioxidant composition comprises 9,10- dihydroanthracene and a metal #-diketone complex of formula where M is a metal, n is 2 or 3, R 2 is H or C 1-20 alkyl and R 1 , R 3 are C 1-10 alkyl, aryl or alkoxy, or C 6-10 aryl groups, the molar ratio of 9,10- dihydroanthracene to complex being 800 : 1 to 20 : 1. The metal may be Cu(II), Ni(II), Co(III) or Al(III), and the complex may be an acetylacetonate. The composition may be used in an amount of, e.g. 50-150 millimoles per litre to stabilize mineral and synthetic ester lubricating oils. In specific examples, liquid paraffin and caprylic acid/1,1,1-trimethylol propane/sebacic acid complex ester are stabilized using 9,10-dihydroanthracene and acetylacetonates of the above metals.
