| Abstract: | Terephthaloyl chloride was synthesized by reaction of terephthalic acid with thionyl chloride under ultrasonic irradiation using pyridine as catalyst. The optimum conditions for synthesis of terephthalyol chloride were as follows： the dosage of terephthalic acid 0.1 mole,irradiation power 250 W, volume of thionyl chloride 40 mL,reaction temperature 80℃ ,reaction time 3 hours. The product yield was up to 92% under the above conditions. The product was characterized by melting point apparatus, IR, 1H NMR and elemental analysis. |
