Abstract

"In this study, development of a polymeric bi-functional porous catalyst that can be used in various applications such as batch, packed-bed, and continuous flow reactors and the formation of highly important chemicals that have many applications in the industry. With this material many homogenous reactions can be conducted in heterogeneous environment which is more efficient and profitable. The catalyst was formed by grafting hollow fiber with APS then immobilized with Br using 1,2-dibromoprobane (Br/APS/PAI-HFs). The formed catalyst was tested with BET and FTIR to confirm the immobilization of Br. A porous polymeric material Br/APS/PAI-HFs provides the ability for ring opining of the propylene carbonate when it reacts with aniline to produce N-Phenylglycine in different reactors. Another, function to the catalyst is carbonation which is demonstrated when CO₂ reacts with propylene oxide in pressurized batch process to form Propylene carbonate with the purpose of continuing the reaction to produce N-Phenylglycine. The final part of this study is to demonstrate a continuous flow microreactor and to study the efficiency of the catalyst in such process compared to other reactors. The results show high conversion of aniline in batch reactor also a 100% conversion of propylene oxide in the first step of the batch system and +99% selectivity. For the continuous flow reactor, it appears to be very efficient to conduct such a process as the results shows high conversion and selectivity in such short time compare to the other two reactors"--Abstract, page iii.
