Abstract

1,180,387. Lubricants. BRITISH PETROLEUM CO. Ltd. 10 July, 1967 [21 July, 1966], No. 32740/66. Heading C5F. A lubricating composition comprises an ester basestock consisting of a liquid neutral polyester that has been prepared by reacting together under esterification conditions and in one or more stages: (i) an aliphatic mono- and/or polyhydric alcohol having 5-15 carbon atoms per molecule and having no hydrogen atoms attached to any carbon atom in a 2-position with respect to any -OH group and (ii) an aliphatic mono- and/or polycarboxylic acid having 2-14 carbon atoms per molecule, the basestock having dissolved therein an antioxidant composition consisting essentially of: (a) 0À5 to 5À0% wt. of an alkylated diphenylamine antioxidant; (b) 0À5 to 4À5% wt. of an alkylated phenyl naphthylamine antioxidant, the total concentration of (a) and (b) being between 1À0 and 8À0% wt.; (c) 0À005 to 1À5% wt. of a copper passivator; (d) 0À5 to 5À0% wt. of a neutral organic phosphate of the formula (RO) 3 PO, where the groups R are tolyl groups, phenyl groups, xylyl groups, or alkyl or cycloalkyl groups having up to 10 carbon atoms; and (e) 0À01 to 5À0% wt. of a dispersant polymer. The ester may be prepared by reacting one or more of the following: 2: 2: 4-trimethylpentanol, neopentyl alcohol, neopentyl glycol, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and di-pentaerythritol with one or more of the following: caprylic acid, capric acid, caproic acid, enanthic acid, pelargonic acid, valeric acid, pivalic acid, propionic acid, butyric acid, 2-ethylhexanoic acid, adipic acid, sebacic acid and azelaic acid. The copper passivator may be imidazoles, pyrazoles, triazoles, salicylaldehyde semicarbazone or a C 1 -C 20 alkyl derivative thereof, and condensation products of salicylaldehyde and a hydrazine derivative or a fatty acid salt thereof such as a C 13 -C 18 fatty acid salt of 1-salicylalaminoguanidine. The dispersing agent may be acrylate and methacrylate polymers, N-vinyl pyrrolidone/acrylate or methacrylate copolymers and N-vinyl pyrrolidone/olefin copolymers. The lubricant may also contain a lead corrosion inhibitor, e.g. a C 1 -C 20 alkyl gallate, neopentyl glycol disebacate, sebacic acid and quinazarin; hydrolytic stabilizers, e.g. amines of formula R<SP>4</SP>(R<SP>5</SP>)NR<SP>6</SP>, where R<SP>4</SP> and R<SP>5</SP> are C 1 -C 4 alkyl groups and R<SP>6</SP> is an alkaryl or hydroxy-substituted alkaryl group having up to 20 carbon atoms such as 2,6-ditertiarybutyl-4-dimethylaminomethyl phenol; and silicones.
