CA 2586083

The invention relates to novel (benzo)triazole compositions comprising mixtures of benzotriazoles and N-substituted benzotriazoles in functional liquids, e.g. mineral oil. The mixtures can be prepared from readily obtainable starting materials, such as tolutriazole (TTA), alkyl aldehydes and cycloalkanols. The invention furthermore relates to a process for protecting metals, which are in contact with functional liquids comprising the mixtures.

La présente invention décrit de nouvelles préparations à base de triazole ou de benzotriazole. Lesdites préparations comprennent des mélanges de benzotriazoles et de benzotriazoles N-substitués dans des liquides fonctionnels, par exemple de l~huile minérale. Lesdits mélanges peuvent être synthétisés à partir de produits de départ commercialement disponibles, tels que le tolytriazole (TTA), des alkylaldéhydes et des cycloalcanols. La présente invention a en outre pour objet un procédé de protection des métaux au contact de liquides fonctionnels comprenant lesdits mélanges.
