Abstract

Sludge-deposition in mineral lubricating oils is inhibited by incorporating therein a small proportion of an acylated polyamine containing at least 14 carbon atoms and of general formula A-NH-X-NH-B, where A represents a naphthenic acid acyl group, B represents a naphthenic acid acyl group or hydrogen, X represents an aliphatic chain containing at least 2 carbon atoms and, if desired, internal linkages such as O-, -S-, -S-S, -SO-, -SO2-, -NH- and -NR-, wherein R represents an aliphatic group or a naphthenic acid acyl group, the two nitrogens in the general formula being bonded to separate carbon atoms in X. Suitable acylated polyamines are the naphthenic acid amides of ethylene diamine, 1 : 2-propylene diamine, 2 : 3-butylene diamine, hexamethylene diamine, diethylene triamine, triethylene tetramine, di-N-(g -aminopropyl)-methylamine, di-(b -aminoethyl)-sulphide, 2 : 3-hexylene diamine, b : b 1 - di - (aminoethyl) - sulphoxide, b : b 1-di-(amino-isopropyl) sulphone, b : b 1 - di - (amino - ethyl) ether, b -aminoethyl - aminoethyl-b 1-aminoethyl ether, and b : b 1-di-(amino-isopropyl) disulphide. Other substances such as pour point depressants, corrosion inhibitors, oiliness agents and extreme pressure agents may be incorporated in the mineral lubricating oils. The acylated polyamines may be prepared by the action of the naphthenic acid, its halide, nitrile or ester on the polyamine.
