This research includes the preparation of Schiff bases from heterocyclic compounds using furfural by the traditional method (sublimation), where mono- and diamine compounds were used. The compounds were diagnosed using FT-IR, 1H-NMR, 13C-NMR, UV-Vis Mass, and SEM to determine the shape of the molecule and whether it is nanoscale. The biological activity that showed moderate to high inhibitory ratios were also evaluated, and measured the molar electrical conductivity of some of them was.

This research includes the preparation of esters and loading of polymers through the reaction of amino acids derived from furfural with alcohols and polyvinyl alcohol by the traditional method (sublimation). 1:1 mol) and then reacts the product of Schiff's bases with the anhydride. The compounds were diagnosed using infrared spectroscopy (IR), nuclear magnetic resonance (1H, 13C-NMR), UV-Vis spectroscopy, and mass spectrometry (Mass). Laser bombardment was also performed using a scanning electron microscope (SEM) to determine the shape of the particle and whether it was a nanoparticle or not. Also, the biological activity was evaluated on four types of karma-positive and gram-negative pathogenic bacteria, which showed moderate to high inhibitory ratios and measured the molar electrical conductivity of some of them. The products were confirmed by the physical changes that occurred to them, such as color, molecular weight, and melting point.
