| Summary: | Abstract<br /> The main object of the study is concerned with studying optimal conditions for the azo dyes formed by the reactions of the mother compound 2,4-dihydroxy benzaldehyde and its twelveth imine derivatives in the forms of oxime and Schiff bases by the spectrophotometric method, at different experimental pH,s. <br /> This study include several experimental factors as volume of reagent, best volume of a Na2CO3 base to obtain the desired pH, order of addition, development time with stability period and optimal wavelengths of the dye complexes. The study comes to a conclusion that each of the experimental factors just mentioned depends primaraly on the chemical structure of imines.<br /> The stoichiometry for all formede dyes under study, are determined by using a mole ratio method and founded to be of types 1:1. |
