ABSTRACT:
The invention relates to the use of N,N'-bis-salicyloyl hydrazine as a metal deactivator for organic materials which are in contact with copper or contain copper or copper ions, and has the object of providing an N,N'-bis-salicyloyl hydrazine which allows processing without danger on an industrial scale. For this purpose, the invention provides an N,N'-bis-salicyloyl hydrazine which is prepared from salicylic-acid alkyl ester and either hydrazine or salicylic-acid hydrazide. N,N'-bis-salicyloyl hydrazine prepared in this manner serves particularly as a metal deactivator in cable and wire insulation for power and communications engineering.
