The College of Education for Pure Sciences, Department of Chemistry, organized a scientific lecture on (preparation and study of the physical properties of implicit complexes between cyclodextrins and Schiff bases derived from anthranic acid)
The lecture presented by the researcher (Mohammed Hafez Hamid) included the preparation of two Schiff bases derived from the reaction of para-aminobenzoic acid with each of ethylvanillin (M1) and ortho-vanillin (M2).
Preparation of three implicit complexes of each of the two bases with (α-CD, β-CD and 2HP-β-CD) by the two methods of lyophilization (Freeze drying) and Co-precipitation and comparison of the physical properties of the prepared Schiff bases in their free and complex conditions with Dextrins (α-CD, β-CD, and 2HP-β-CD) to know the effect of complex formation on the solubility of these compounds, which is known by its low water solubility.
Calculation of the particle and particle size as well as their area based on XRD and SEM data.
The lecture recommended conducting some physical tests, such as a study of the natural fluorescence of the bases, showing the presence and absence of cyclodextrins.
Second: Using other methods to prepare implicit complexes with different cyclodextrins and studying the nature of their interaction.
