| Abstract: | The sulfonated polyaryletherketoneketone(S PEKK) was synthesized from cross linked polyaryletherketoneketone with 20% fuming sulfuric acid, and then it was used as catalyst in esterification of fumaric acid and methyl alcohol. The optimum reaction conditions were obtained as follows: fumaric acid 11.6 g, methyl alcohol 40 mL, S PEKK 3.0 g, reaction temperature 8595 ℃, reaction time 5 h. The esterification yields reached 89.3% and the catalyst could be recovered easily and be reusable. |
