2-Ketopentafluoropropanesulfonic acid is obtained as a product of the reaction of sulfur trioxide and ethyl pentafluoroisopropenyl ether or by transesterification from corresponding esters. Similar sulfonic acids may be obtained by the latter process. The new compounds are useful as monomers for producing polymers, particularly moldable, dyeable, fluoropolymers, and as cationic initiators, e.g., for tetrahydrofuran polymerization.
2-酮基五氟丙烷磺酸是由三氧化硫和乙基五氟异丙烯醚反应产生的产物,或通过相应酯的酯交换反应得到。类似的磺酸也可以通过后一种方法获得。这些新化合物可用作生产聚合物的单体,特别是可塑性、可染色、氟聚合物,以及作为阳离子引发剂,例如用于四氢呋喃聚合。
