资源简介：
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 (<sup>1</sup>H and <sup>13</sup>C NMR), the thermal stability identified by thermogravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were all used to thoroughly analyze the manufactured product.
