Perfluoroalkyl compounds containing ether groups have the formula R.sub.f R.sub.1 SCH.sub.2 CH.sub.2 O T Z wherein R.sub.f is a perfluoroalkyl, R.sub.1 is alkylene or alkyleneoxy or aminoalkylene, T is alkylene, and Z is hydrogen; hydroxy; NR.sub.3 R.sub.4, where R.sub.3 and R.sub.4 each is alkyl or together with nitrogen form a heterocyclic ring; N.sup.+ R.sub.3 R.sub.4 (R.sub.5)X.sub.z.sup.-y, where R.sub.5 is hydrogen, oxide, alkyl, or substituted alkyl, X is an anion, and y is 1 or 2; z is 0 or 1 or is --OCH.sub.2 CH.sub.2 SR.sub.1 R.sub.f ; can be prepared directly by free-radical catalyzed addition of a perfluoroalkylthiol to a vinyl ether or subsequent reaction. These compounds are useful as surfactants and oil spill collecting agents.
含有醚基的全氟烷基化合物的化学式为R.sub.f R.sub.1 SCH.sub.2 CH.sub.2 O T Z,其中R.sub.f是全氟烷基,R.sub.1是烷基或烷氧基或氨基烷基,T是烷基,Z是氢;羟基;NR.sub.3 R.sub.4,其中R.sub.3和R.sub.4各自是烷基或与氮一起形成杂环;N.sup.+ R.sub.3 R.sub.4 (R.sub.5)X.sub.z.sup.-y,其中R.sub.5是氢、氧化物、烷基或取代烷基,X是阴离子,y为1或2;z为0或1或为--OCH.sub.2 CH.sub.2 SR.sub.1 R.sub.f;可以通过自由基催化的全氟烷基硫醇加成到乙烯醚或随后的反应直接制备。这些化合物可用作表面活性剂和溢油收集剂。
