| Abstract: | Pentabromobenzyl acrylate was prepared using toluene as material, via the processes of hromination and esterification. Using chloroform as solvent, pentabromotoluene was firstly synthesized, which was subsequently brominated in carbon tetrachloride, initiated by ultraviolet and AIBN. The resulting intermediate product pentabromobenzyl bromide was then estefified with acrylic acid and polymefized to prepare the ultimate product. The esterification reaction was conducted in chlorobenzene, in the presence of phase transfer catalyst and inhibitor. The structure of pentabromobenzyl acrylate was characterized by NMR and FT-IR. |
