Abstract
Als Korrosionsschutzmittel in Schmierölen und Schmier
fetten auf Mineralölbasis werden Reaktionsprodukte aus
a) konjugiert mehrfach ungesättigten Fettsäureestern,
die im Fettsäurerest 16 bis 22 C-Atome und im alkoholischen
Rest 1 bis 10, vorzugsweise 1 bis 4 C-Atome enthalten,
und
b) Fumarsäure sowie
c) nachfolgender weiterer Umsetzung mit Ammoniak
und primären beziehungsweise sekundären Aminen mit
Alkylresten der Kettenlängen 1 bis 22 C-Atomen oder
anstelle von c) mit Alkoholen verwendet. Es werden Mengen
von 0, 1 bis 10 Gewichtsprozent - bezogen auf die Mineralöl
basis - eingesetzt. Reaction products are used as anti-corrosion agents in lubricating oils and greases based on mineral oils
a) conjugated polyunsaturated fatty acid esters containing 16 to 22 C atoms in the fatty acid residue and 1 to 10, preferably 1 to 4 C atoms in the alcoholic residue,
and
b) fumaric acid and
c) subsequent further reaction with ammonia and primary or secondary amines with alkyl radicals with chain lengths of 1 to 22 carbon atoms or used instead of c) with alcohols. Quantities of 0.1 to 10 percent by weight, based on the mineral oil base, are used.
