Therefore, it possible use as photothermally activated Fischer triglyceride transesterification (biodiesel synthesis).

Abstract: Important organic reactions require the use of catalysts. The Friedel-Crafts were discovered by Charles Friedel and James Mason Crafts in 1887. They are an essential catalytic process since they widely applied different areas such as fuels, cleaning, pharmacological products. reaction is usually carried out presence Lewis acids or Brønsted a homogeneous medium, with nucleophilic aromatic substrate excess. Although there still work literature on Friedel- medium using metal halides, tendency to replace these catalysts, which generate effluents that harmful environment. Heterogeneous catalysts solid show advantages over especially concerning separating products from recycling, reusing. This paper presents mini-review focusing reactions.
