| description | This report discusses the synthesis of a biosourced divanillin derivative obtained by Knoevenagel condensation. The compound was fully characterized by proton (<sup>1</sup>H), carbon (<sup>13</sup>C), heteronuclear single quantum coherence (HSQC), homonuclear correlation spectroscopy (COSY), and heteronuclear multiple bond correlation (HMBC) NMR, as well as high-resolution mass spectroscopy (HRMS). We also investigated the optical properties through UV-visible spectroscopy and Fourier-transform infrared (FTIR) spectroscopy. At last, the thermal properties of this divanillin derivative were evaluated by thermogravimetric analysis (TGA) as well as differential scanning calorimetry (DSC). |
