Abstract (en)
A cooling lubricant which contains, as an extreme-pressure additive, an alkali metal salt or alkaline earth metal salt of a compound of the formula <IMAGE> is distinguished by an improved additive effect as compared with products which contain amine salts. It is free of diethanolamine and can therefore not form any nitrosamine in use.
Abstract (de)
Ein Kühlschmierstoff, welcher als EP-Additiv ein Alkali- oder Erdalkalisalz einer Verbindung der Formel <IMAGE> enthält, zeichnet sich durch eine bessere Additivwirkung aus im Vergleich zu Produkten, die Aminsalze enthalten. Er ist frei von Diethanolamin und kann deswegen beim Einsatz kein Nitrosamin bilden.
