Title: Innovations of Jung Keun Lee in Catalysis
Introduction
Jung Keun Lee is a notable inventor based in Ulsan, South Korea. He has made significant contributions to the field of catalysis, particularly through his innovative approaches to modifying halloysite catalysts. With a total of three patents to his name, Lee's work is recognized for its efficiency and effectiveness in chemical production processes.
Latest Patents
One of Jung Keun Lee's latest patents involves a supercritical carbon dioxide morphologically modified acid-based halloysite catalyst. This invention focuses on the efficient production of poly(tetramethylene ether) diacetate (PTMEA) or other diesters from tetrahydrofuran (THF). The catalyst is derived from a morphologically reconfigured and Bronsted acidity enhanced halloysite, utilizing a preparation method that incorporates naturally occurring halloysites. The method specifically addresses the morphological modification of the internal pore structure of halloysites through supercritical carbon dioxide treatment. This innovative approach yields highly synergistic and reproducible results by eliminating inaccessible and detrimental extra-small pores. Furthermore, PTMEA can be readily converted to poly(tetramethylene ether) glycol (PTMEG) through a transesterification reaction.
