Synthesis and Anti-corrosion Research of 2,5-Bis(benzylidenehy-drazino)-1,3,4-thiadiazole Compounds

Abstract

2,5-Dihydrazino-1,3,4-thiadiazole was prepared by 2,5-dimecapto-1,3,4-thiadiazole and hydrazine, and then the six novel different 2,5-bis(benzylidenehydrazino)-1,3,4-thiadiazole compounds were obtained by a condensation reaction of 2,5-dihydrazino-1,3,4-thiadiazole with substituted benzaldehyde and structurally confirmed by elemental analysis, IR,¹H NMR and mass spectra. The result indicates that the six 2,5-bis(benzylidenehydrazino)-1,3,4-thiadiazole compounds are of definite inhibition against silver surface in corrosion jet fuel.

Key words: hydrazine, anti-corrosion, benzaldehyde, 2,5-dimercapto-1,3,4-thiadiazole, synthesis, aldehyde-hydrazone
