“…According to the data presented in Figure 3, the effective values of the dissociation constants (pKa) of various forms of HAL are calculated and to be 7.5 and 11.2, which is consistent with the previously obtained results described in [24]. The tangent of the slope angle of the dependence under study is 0.0589, therefore, one proton and one electron participate in the electrode process [25,26]. On the presented Table 1.…”

The electrochemical behavior of a number of benzoyl barbiturates was studied using a glassy carbon electrode (GCE). The kinetics of the electrode process is determined, the contribution of physical adsorption to the electrochemical process is estimated, and the mechanism of the possible electrochemical reaction is proposed. It is shown that the electrochemical reduction potentials of benzoyl phenobarbital derivatives are determined by the LUMO energies, calculated by the B3LYP 6‐311+G method. It is established that the process is quasi‐reversible, complicated by adverse reactions. The influence of halogen type and its position in the benzoyl residue of the studied substances on the analytical signal is established. The effective values of the dissociation constants of various forms of benzoyl derivatives were calculated using the example of halonal, for which the values 3.16 ⋅ 10−8 and 6.31 ⋅ 10−12, respectively, were found.
