摘要:

ＨＦ与铝硅酸盐的反应一直被认为是十分简单的一步反应，但它的副产物氟硅化物和氟铝化物的后继反应却是十分复杂的，通过＾１９ＦＮＭＲ对各物种的分布情况的分析，可完全认识土酸酸化的实际溶液化学行为。本文简要回顾了砂岩酸化反应动力学的历程。介绍了近年来国外在这方面所作的最新研究成果。

Abstract:

Reaction of HF on aluminium silicate is always considered to be a simple one-step reaciton, but the succeed reaction of its by-product fluoro-silica compund and fluoro-aluminia compound is very complex. After analizing distribution of every species by ~(1
