Title: HYDROPHOBIC POLYMER-SUPPORTED LEWIS ACID CATALYST AND PROCESS FOR THE PREPARATION THEREOF
Abstract:
The patent discloses a hydrophobic poly(AA-co-DVB) supported Lewis acid as a heterogeneous catalyst for anhydrous reaction. These unmodified polymer and polymer-supported Lewis acid catalysts were characterized by different techniques such as surface area, thermal degradation, glass transition temperature, reactivity, and swelling behaviour. Hydrophobic and more reactive polymer was selected for the use as a catalyst in anhydrous reaction. Overall, the invention relates to a process for the synthesis hydrophobic poly(AA-co-DVB) supported Lewis acid catalyst and its use for anhydrous reaction.
