摘要：

The pK (a) values of some phthalhydrazide derivatives were calculated using ab initio and two density functional methods to obtain information about their reaction conditions. The results showed that pK (a1) was influenced by structural modification as it varied between 0.47 and 6.99, and that pK (a2) was relatively less variable from 16.66 to 21.53. The high values of pK (a2) revealed that a strong alkaline solution was necessary for all chemiluminescent reactions of discussed phthalhydrazide derivatives.
