SYSTEMES STABILISANTS, POLYALKYLENE-GLYCOLS QUI EN CONTIENNENT, ET APPLICATION DE CES SYSTEMES A LA STABILISATION DE POLYALKYLENE-GLYCOLS

摘要

A stabilizer system containing at least one compound of the formula I (I) and one compound of the formula II (II) the substituents R1, R2, R and R' having the meanings defined in the text, and x being 1 to 3. This stabilizer system is suitable for use as an additive to a polyalkylene glycol base liquid for preventing the formation of rust, especially on iron-containing surfaces, the use of these lubricant compositions being possible also in the high-temperature range.
