The main work and the conclusion of the article are : ( 1 ) give a suggestion on the reaction mechanism and the principle of catalyst selection. ( 2 ) by comparison of the catalyst activity of solid superacid with the zinc oxide, stannous chlorde and tin ( ii ) octate in the synthesis reaction. we find that although its activity is lower than tin ( ii ) octate, obviously higher than that of traditional zinc oxide and stannous chlorde. from the point of preparation cost, we select solid superacid as catalyst
但從催化劑的制備成本和工藝的角度選擇，固體超強酸具有明顯的優勢； （ 3 ）制備一系列單組元和雙組元硫酸促進氧化物固體超強酸，並用於丙交酯的合成反應，篩選具有最佳活性的固體超強酸催化劑： （ 4 ）使用so2 - 4 / zno - sno2 （ 2 ： 1 ） la3 +固體超強酸作催化劑，反應脫水時間1 -
Abstract : by comparing the dehydration methods of three catalytic by comparing the dehydration methods of three catalytic esterification reactions and the catalysts used under negative by comparing the dehydration methods of three catalytic esterification reactions and the catalysts used under negative pressure, the better method of synthesizing 2 - ethylhexyl chloroacetate is using stannous oxide as catalyst under negative chloroacetate is using stannous oxide as catalyst under negative pressure
文摘:通過對三種催化酯化反應的脫水方法及負壓下使用不同催化劑的比較和通過對三種催化酯化反應的脫水方法及負壓下使用不同催化劑的比較和選擇，提出了以氧化亞錫為催化劑負壓脫水合成氯乙酸2 -乙基己酯的方法。
