節(jié)能減排、安全環(huán)保，己二酸二甲酯的 生產(chǎn) 工藝設備也在 不斷的提高改進中， 對于我國來說，隨著國民經(jīng)濟的不斷發(fā)展及人民生活水平的不斷提高，應積極 探索 酯化反應工藝及相關設備 ，加強對新興酯化工藝的研究， 掌握和運用國內(nèi)外的先進酯化及應用技術，這對 我國己二酸二甲酯生產(chǎn)乃至整個酯化反應工業(yè)都會產(chǎn)生極大的影響。 所以近二十年來 ，固體超強酸一直是研究的熱點。 李平等 [7]將工業(yè)上常用的幾種強酸性陽離子樹脂在己二酸二甲酯合成反應中的催化活性和穩(wěn)定性進行綜合比較，篩選出了適合己二酸二甲酯制備用催化劑。 樊麗華 等 [9]以己二酸和無水甲醇為原料，一水合硫酸氫鈉
