Abstract

Als Korrosionsschutzmittel in Schmierölen und Schmier­ fetten auf Basis von Mineralölen sind Monoamide von Adduk­ ten aus einfach oder mehrfach ungesättigten Fettsäuren (C₁₆₋₂₂) und Maleinsäureanhydrid bzw. Fumarsäure bean­ sprucht, die durch Umsetzung der Säuren mit Ammoniak, pri­ mären oder sekundären Alkylaminen (C₁₋₂₂) zu Monoamido-di­ carbonsäuren hergestellt werden. Bevorzugt sind Umset­ zungsprodukte mit Alkylaminen (C₈₋₂₀), z.B. Dibutyl-, Ethylen­ hexyl-, Dodecylamine. As a corrosion protection agent in lubricating oils and lubricants greases based on mineral oils are monoamides from Adduk from mono- or polyunsaturated fatty acids (C₁₆₋₂₂) and maleic anhydride or fumaric acid bean says that by reacting the acids with ammonia, pri mary or secondary alkylamines (C₁₋₂₂) to monoamido-di carboxylic acids are produced. Implementation is preferred products with alkylamines (C₈₋₂₀), e.g. Dibutyl, ethylene hexyl, dodecylamines.

Die Derivate sind viskose, in Mineralöl lösliche Öle; sie werden in Mengen von 0,1-10 (1-2)%, bezogen auf Mineralöl­ basis, angewandt. The derivatives are viscous oils that are soluble in mineral oil; they are in amounts of 0.1-10 (1-2)%, based on mineral oil base, applied.

Herstellungsbeispiele und Prüfung des Korrosionsgrades beim Einsatz in Schmierölen. Manufacturing examples and checking the degree of corrosion when used in lubricating oils.
