摘要
本文研究了全氟(2,5-甲基-3,6-二氧杂-8-氟磺酰基辛酰氟)(2)在溶剂存在下与碳酸钠的裂解反应,反应分两步进行,第一步,2在60℃下与Na_2CO_3反应生成羧酸钠盐(4),第二步,4在180—220℃下脱羧,我们分离鉴定了裂解产物,并探讨其反应机理,在研究副产物砜的形成的基础上,合成了一系列含氟砜。
The pyrolysis of perfluoro(2, 5-dimethyl-3, 6-dioxa-8-fluoro sulfonyl octanoyl fluoride) (2)in the presence of Na_2CO_3 in a solvent was studied. The reaction took place in two steps, i.e. first, compound 2 reacted with sodium carbonate at a temperature of 60℃ to form the sodium carboxylate 4, then, which was decarboxylated at a temperature of 180—220℃. The various reaction by-products were separated and identified, and the eaction mechanism was studied.
