Abstract: Based on DFT, B3LYP method was used to optimize the structure of 3-tert-butyl-4-hydroxyanisole (BHA) mol. at the level of 6-311g(d,p) set level. On this basis, the first 50 excited states were calculated by using B3LYP/def 2-TZVP method based on TD-DFT with ethanol as solvent. Multiwfn 3.6 software was used to plot the UV spectrum, and three methods including at. charges, Fukui function (FF) and electrostatic potential (ESP) were used to predict its electrophilic reactive sites. Finally, bond energy of O10-H11 and C12-O13 were investigated by the ωB97XD/TZVP method. Comparing the exptl. and theor. UV spectra, it was found that the overall agreement was good. The oxygen atom on the phenolic hydroxyl group and the oxygen atom on the ether bond are the electrophilic reactive sites. And the C12-O13 bond on the ether bond is more prone to dissociation They are easily reacted with peroxide radicals to have oxidation resistance.
