Melting point depression of tetrabutylammonium halides in supercritical carbon dioxide
Ionic liquids could be promising for biphasic reaction media and CO₂ capture, where understanding phase behavior under supercritical CO₂ is essential for high-pressure applications.

Semi-continuous hydrothermal terephthalic acid recovery from poly(ethylene terephthalate)
Our research group has conducted extensive research on the semi-continuous hydrolysis of polycondensation polymers, in an effort to design chemical recycling processes for plastic waste streams that are difficult to recycle with conventional methods. In this work, we designed a novel non-catalytic semi-continuous process for the selective hydrolysis of polyethylene terephthalate (PET). The main highlights of the work are the stablising alkaline quench stream ensuring stable operation and simple product separation, and deconvolution calculations to demonstrate that the process limiting step is not the solubilisation of the reaction products.
