根据最近的实验，包括13C标记的烷烃的同位素分布模式以及烷烃与D2O交换催化剂之间的钚/氚交换，发展了小烷烃在强固体酸或超强酸上转化的各种机理。通过与液体超强酸实验的对比，讨论了两种催化剂在烃类化学方面的异同，以及导致催化剂失活的初始步骤。
Various mechanistic aspects of small-alkane transformations on strong solid acids or superacids are developed in light of recent experiments involving isotope distribution patterns in13C-labelled alkanes and protium/deuterium exchange between alkanes and D2O-exchanged catalysts. In comparison with experiments using liquid superacids, similarities and differences in hydrocarbon chemistry between the two types of catalysts are discussed as well as the initial steps leading to catalyst deactivation.
