1. Introduction In the last decades, a great effort has been concentrated to replace the mineral acids in homogeneous organic esterification reactions with the heterogeneous catalysis using super acid catalysts [1–6]. The advantages for heterogeneous catalysis over those performed in the presence of mineral acids may be pointed in:
(i) Unlike the homogeneous catalysis, it does not include toxicity, corrosiveness, difficulty in separation mixture and reusability.
(ii) The corrosive environment will be a minimal.
(iii) The catalyst can be easily filtered off and the product will be highly pure where the actual exclusion of the side reactions is expected.

介绍在最后十年, 一个棒的努力已经被集中撤换无机酸在同种的有机酯化反力由于多相催化使用非常的酸催化剂 [1-6]. 对于在无机酸之前被执行的那些上的多相催化的优点可能被指出在:
(i)不像均相催化,它不含毒性,腐蚀, 分离混合物和再可用性的困难。
(ii) 腐蚀的环境将会是极小。
(iii) 催化剂能容易地被过滤滑落和生产品将会是高度地纯粹的侧反应的实在除外责任条款被期望的地方。
