With a total of two patents to his name, Lee's work is recognized for its efficiency and effectiveness in chemical production.

Latest Patents

Hwan Bock Lee's latest patents focus on the development of a supercritical carbon dioxide morphologically modified acid-based halloysite catalyst. This catalyst facilitates the efficient production of poly(tetramethylene ether) diacetate (PTMEA) and other diesters from tetrahydrofuran (THF). The innovative method involves the morphological modification of the internal pore structure of halloysites using supercritical carbon dioxide treatment. This process enhances the Bronsted acidity of the halloysite, yielding highly synergistic 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.
