| Abstract | ||
| The main objective of this paper was to establish the factors affecting the rate constant for the reaction of six sulpha drugs with p- dimethylaminobenzaldehyde (DAB) through correlation analysis. Four parameters belonging to the sulphonamides have been suggested. The first was taking the type of sulphonamide amino group (N) primary, secondary, or tertiary. The second was for steric effect (M) which takes the number of the bulky methyl group into account. The third was the molecular weight (m.wt) of the sulphonamide molecule. The last one was belonging only to metal effect (S) for the sulphonamide containing metal ion. The correlation analysis was applied to the reaction of sulphonamide in the absence and presence of anionic surfactant (Sodium dodecyl sulphate, SDS). The results show that the parameter M is the predominant one in absence of SDS, while in the presence of SDS; N parameter is the predominant one. Additive parameters for the rate constant of these reactions in the absence and presence of SDS have been suggested with good standard devia | ||
