Abstract: 1467276 Lubricants SNAMPROGETTI SpA 8 May 1974 [9 May 1973] 20392/74 Heading C5F [Also in Division C3] Lubricants contain, as anti-sludge additive, nitrogen containing reaction products prepared by esterifying one of the two carboxyl groups of a dicarboxylic acid with a homo- or co-polymer of an epoxide or glycol. The other carboxyl group is converted to a substituted or unsubstituted ammonium salt or to an amidic or amidinic group by reaction with ammonia, an aliphatic, aromatic or cyclic monoamine or a linear or cyclic polyamine. The polymer may be derived from ethylene oxide or glycol, propylene oxide or glycol or butylene oxide or glycol. Suitable acids are succinic, maleic or phthalic acids. Amines exemplified are triethylamine, tetraethylenepentamine and cyclohexylamine. Examples relate to the use of the compounds of the invention as anti-sludge additives for synthetic lubricants for a petrol engine.
