三氧化硫和四氟乙烯反应生成四氟乙烷磺内酯,反应方程式如下: (?) 某厂按上述反应生产四氟乙烷磺内酯时,曾发生一次猛烈爆炸。1971年杜邦公司也曾报导~([1])类似的事故。他们指出三氧化硫和四氟乙烷磺内酯的混合物是不稳定的,尤其是摩尔比为1:1时易爆炸,要避免灼热和火种。爆炸反应按下式进行: (?) 为了探讨爆炸起因,我们进行了爆炸模拟实验,并根据爆炸现场情况,推论了引起爆炸的原因。
Sulfur trioxide reacts with tetrafluoroethylene to produce tetrafluoroethane sultone. The reaction equation is as follows: (?) A violent explosion occurred when a plant produced tetrafluoroethane sultone by the above reaction. In 1971 DuPont also reported ~ ([1]) similar incidents. They point out that the mixture of sulfur trioxide and tetrafluoroethanesulfonolactone is not stable, especially when the molar ratio is 1: 1, it is easy to explode, to avoid burning and burning. Explosion reaction according to the following formula: (?) In order to explore the cause of the explosion, we conducted an explosion simulation experiments, and infer the cause of the explosion according to the scene of the explosion.
