摘要
以对苯二甲酸和氯化亚砜为原料,以吡啶为催化剂,超声辐射合成对苯二甲酰氯。得出合成对苯二甲酰氯的最佳条件:对苯二甲酸用量0.1 mol时,在超声功率250 W下,氯化亚砜40 mL,温度80℃,时间3 h,产品收率最高可达92%。用熔点仪、红外光谱,核磁共振谱及元素分析对产物进行了表征。
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.
