摘要
The invention relates to a process for the inhibition of corrosion on copper or copper alloy surfaces. Such a surface is placed in contact with a compound conforming to Formula I: ## STR2 ## IN WHICH R REPRESENTS HYDROGEN OR -SH, AND R REPRESENTS A RADICAL ALKYL, CYCLOALKYL, ARALKYL, PHENYL, NAPHTHYL, PYRIDYL, MORPHOLINYL, PYRROLIDINYL, PIPERIDYL, PERHYDROAZEPINYL OR TRIAZOLE-1,2,4 YLE-4, AND, WHEN R REPRESENT THE HYDROGEN, R MAY ALSO REPRESENT A RADICAL (TRIAZOLE -1,2,4 YL-3) -ARYLENE, A RADICAL TRIAZOLE-1,2,4 YLE-3 OR A RADICAL (TRIAZOLE-1,2,4 YL-3) -ALKYLENE OF WHICH THE ALKYLENE PART IS POSSIBLY INTERRUPTED BY OXYGEN, NITROGEN OR SULFUR ATOMS. / P P THESE COMPOUNDS MAY BE ADDED, FOR EXAMPLE, TO LUBRICANTS, HYDRAULIC LIQUIDS, TO LIQUIDS FOR THE MACHINING OF METALS, WATER-BASED COOLING LIQUIDS FOR MOTORS OR OILS FOR TRANSFORMERS OR CIRCUIT BREAKERS. / P
