This article deals with various ‘supported’ acid catalysts developed as alternatives for the conventional ones in organic synthesis. They have advantages such as producing less toxic waste and using less energy.
In the first part of this article, the principles of functioning of the solid acid catalysts, their nature and preparation of a few types were described. In this part, some practical examples of such catalysts employed in the synthesis of several organic compounds are presented, which illustrate the extent to which catalysts help reduce pollution, cut costs of production, etc., that are important...
