摘要： A bridged alkaline earth metal alkylphenate having reduced monomeric alkylphenol is prepared by reacting (a) a 4-alkylphenol, unsubstituted at the ortho positions, (b) an alkaline earth metal oxide or hydroxide, (c) a bridging agent comprising sulfur or a carbonyl compound of 1 to about 6, or to 4 or to 2, carbon atoms, and (d) a 2,6-dialkylphenol. The amount of the 2,6-dialkylphenol is 0.05 to 3 moles per 1 mole of the 4-alkylphenol; if there is a molar excess of the 2,6-dialkylphenol, then the excess is added after initial reaction.

摘要： A fluid composition suitable for use as an aircraft hydraulic fluid is disclosed. The fluid composition comprises a fire resistant phosphate ester base stock comprising between about 10% and about 100% by weight of a trialkyl phosphate, between about 0% and about 70% by weight of a dialkyl aryl phosphate, and from about 0% to about 25% by weight of an alkyl diaryl phosphate, with the proviso that the sum of the proportionate amount of each base stock component must equal 100%. The alkyl substituents of the trialkyl phosphate, the dialkyl aryl phosphate, and the alkyl diaryl phosphate contain between 3 and 8 carbon atoms, preferably between 4 and 8 carbon atoms, more preferably between 4 and 5 carbon atoms, and are bonded to the phosphate moiety via a primary carbon. It is still further preferred that the alkyl substituents of the trialkyl phosphate, the dialkyl aryl phosphate, and the alkyl diaryl phosphate are isoalkyl groups. The fluid composition further comprises an acid scavenger, an anti-erosion additive, a viscosity index improver, and an antioxidant. A novel additive combination comprises a high molecular weight butyl/hexyl methacrylate viscos ity index improver, a perfluoroalkylsulfonate anti-erosion additive, a 3,4-epoxycyclohexanecarboxylate or a diepoxide acid scavenger, a di(alkylphenyl)amine, and a phenolic antioxidant comprising a mixture of a 2,4,6-trialkylphenol and a hindered polyphenol compound selected from the group consisting of bis(3,5-dialkyl-4-hydroxyaryl)methane, 1,3,5-trialkyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxyaryl)benzene and mixtures thereof. Preferably, the fluid composition further comprises a benzotriazole derivative as a copper corrosion inhibitor, and a 4,5-dihydroimidazole derivative, as an iron cor rosion inhibitor and to enhance the stability of the fluid.

The specified products include 9,10-bis(3,5-di-tert.-butyl-4-hydroxybenzyl)anthracene, 1,4-bis(3,5- diisoprophyl-4- hydroxybenzyl-naphthalene, alpha-3,5-diisopropyl- 4-hydroxybenzyl-naphthalene, 1-methyl- 3(3-methyl- 5-tert.-butyl- 4-hydroxybenzyl)-naphthalene, 1,4,58- tetra(3,5-di-tert.-butyl- 4-hydroxybenzyl)naphthalene, 9,10-bis(3-methyl- 5-tert.-hexyl- 4-hydroxybenzyl) phenanthrene, 1,4,5,8,9,10- hexa(3,5-diisopropyl-4-hydroxybenzyl)anthracene, and 5,6,11, 12-tetra(3,5- di-tert.- butyl-4- hydroxybenzyl) naphthacene. Products derived from chrysene, pyrene, benzanthracene, pentacene, dibenzanthracene and coronene are also specified. The products are useful as antioxidants and for protecting materials against thermal and ultra-violet degradation. Materials to which the products may be applied include polyolefines, synthetic rubbers and liquid ethylenically unsaturated monomers, a number of each of which are specified, and also natural rubber, gasoline, kerosine, furnace oils, lubricating oils and greases. A synergistic effect is produced if the antioxidants described above are used in association with certain sulphur compounds (see Groups III and IV(a)).
