以杯[6]芳烃为原料,在浓硫酸催化作用下,合成了磺化杯[6]芳烃,并通过红外光谱和核磁共振谱对其进行结构表征。热重分析结果表明,在升温速率为5℃/min 时,磺化杯[6]芳烃开始降解温度为125.62℃,最快降解温度为269.43℃。经过 Kissinger 方程计算,磺化杯[6]芳烃的降解活化能为161.45 kJ/mol。
Sulfonated calix[6]arene was successfully synthesized from calix[6]arene using H2SO4 as catalyst. Structure of sulfonated calix[6]arene was characterized by FTIR and 1H NMR. TGA curves of sulfonated calix[6] arene indicated that the starting decomposition temperature of sulfonated calix[6]arene was 125. 62℃,and the fast decomposition temperature was 269. 43℃. According to Kissinger equation,the thermal decomposition Ea of sulfon-ated calix[6]arene was 161. 45kJ/mol.
