The perfluorosulfonic acid (PFSA) Aquivion PW98 is an amphiphilic solid superacid which is shown to catalyze the conversion of cellulose into amphiphilic alkyl glycosides (AAGs) in 85 % yield (with 97 % selectivity). The process involves a mechanocatalytic depolymerization of cellulose followed by a direct glycosylation with n-dodecanol. In comparison to H SO and solid acid catalysts commonly employed in cellulose processing, Aquivion PFSA PW98 is not only recyclable but also exhibits superior catalytic performances in terms of yield, selectivity, and reactor productivity.
全氟磺酸 (PFSA) Aquivion PW98 是一种两亲性固体超强酸，已被证明可在 85%的收率（97%的选择性）下催化纤维素转化为两亲性烷基糖苷 (AAG)。该过程涉及纤维素的机械催化解聚，然后与正十二醇直接进行糖苷化。与在纤维素加工中常用的 H2SO4 和固体酸催化剂相比，Aquivion PFSA PW98 不仅可回收利用，而且在产率、选择性和反应器生产力方面表现出更优异的催化性能。
