2，5-二苯腙基-1，3，4-噻二唑类化合物的合成及抗腐蚀性能研究

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

以2,5-二巯基-1,3,4-噻二唑为原料,与水合肼反应制得2,5-二肼基-1,3,4-噻二唑,再将其与取代苯甲醛缩合,得到了6种新的2,5-二苯腙基-1,3,4-噻二唑类化合物,其结构经元素分析、红外、^(?)H NMR及质谱等方法所证实.6种噻二唑衍生物对喷气燃料银片腐蚀有一定的抑制作用.

2,5-Dihydrazino-1,3,4-thiadiazole was prepared by 2,5-dimecapto-1,3,4-thiadiazole and hydra- zine, 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.
