Résumé
Antioxidant polyphenols like gallic acid (GA) and its esters called "gallates", which have health advantages for humans, have grown in significance in maintaining a healthy lifestyle and eating a significant amount of secondary plant phytochemicals. Here, for the first time, we suggest a green synthesis of a brand-new, all-natural diester based on gallic acid and polyethylene glycol. This di-gallate is created in a single step without the use of a solvent (solid-solid reaction). This reaction has a potential yield of up to 90%. The bathochromic shift of the absorption bands from 277 nm to 295 nm in the UV-VIS spectra was caused by the addition of PEG to gallic acid. To confirm the structure of this di-gallate; Fourier-transform infrared (FTIR) spectroscopy, proton and carbon nuclear magnetic resonance ( The acquired results, when compared to the literature spectrums, supported the establishment of the di-ester structure and created new opportunities for a large number of applications.
