Abstract (en)
[origin: EP0144739A2] Reaction products of a) conjugated polyunsaturated fatty acid esters, which contain 16 to 22 C atoms in the fatty acid radical and 1 to 10, preferably 1 to 4, C atoms in the alcohol radical, and b) fumaric acid and also c) subsequently reacted further with ammonia and primary or secondary amines having alkyl radicals of chain lengths 1 to 22 C atoms or with alcohols in place of c) are used as corrosion inhibitors in mineral-oil based lubricating oils and lubricating greases. Quantities of 0.1 to 10 per cent by weight - relative to the mineral oil base - are used.
