不同取代基的苯酰肼的感染显影及其机理

本文研究了五种苯酰肼化合物(通式为R-Ph-NHNH-COR')对卤化银乳剂感光性能的影响。利用循环伏安、气-质联仪等方法研究了苯酰肼感染显影的作用机理及其影响因素。实验结果表明,通过苯酰肼的感染显影可获得高感、高反差的效果,影响感染显影程度的大小,除了与取代基R,R’结构有密切关系以外,还与乳剂的种类、胶银比、苯酰肼在卤化银颗粒上的吸附等因素有一定关系。另外也发现苯酰肼衍生物取代基结构不同,其作用机理也不尽相同,从而进一步加深了对感染显影机理的认识。

EFFECT AND MECHANISM OF THE INFECTIOUS DEVELOPMENT CAUSED BY DIFFERENT PHENYLHYDRAZINES

The effects of five phenylhydrazines (general formular:R-Ph-NHNH-COR’)on the photographic properties of silver halide emulsions have been investigated.The mechanisms and influential factors are also studied by cyclic voltammetry and GC-MS spectrometry etc,It is found that the infectious effects caused by phenylhydrazines vary with the change if the substituent R or R’,and have a relation to the gelatin-silver ratio and the type of the emulsion.When the substituent R or R’was changed,the mechanism is different.A more complete understanding of the meachanism of infectious development has been obtaind.
