A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) (see formula I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
L'invention concerne un mélange synergique comprenant 1 à 99,9 % en poids de composés comportant des motifs constitutifs (I), dans lesquels les valences libres sur l'atome d'oxygène et sur l'atome d'azote peuvent être réunies pour former un cycle à cinq, six ou sept chaînons et le noyau benzénique peut encore comporter des substituants sur une ou plusieurs des positions libres, ainsi que 0,1 à 99 % en poids de composés organiques sulfurés à action antioxydante. Ce mélange synergique est adapté comme stabilisateur pour stabiliser une matière organique inanimée, en particulier des produits pétrochimiques et des carburants, contre les effets de la lumière, de l'oxygène et de la chaleur.
