摘要
用全氟树脂和ＳｂＦ５作用得到一种能在常温下使丁烯烷基化，正戊烷异构的固体超强酸催化剂·酸强度为－１６．１２≤Ｈ０＜－１４．５２．用ＸＰＳ测定了催化剂中Ｓｂ的电子结合能，并讨论了超强酸产生的原因．
A superacid polymer was prepared by the reaction of perfluorinated ion exchange polymer with SbF5.Solid superacid strength of acid sites was in the range of -14.52≥H0≥-16.12.It wasobserved that n-pentane can be converted into iso-pentane and iso-butane;butene was alkylated by isobutane into iso-octane at 20 ℃ by contact with it. Electron binding energy of Sb2/3 in SbF5 was researched by XPS.
