Solvothermal liquefaction of waste polyurethane using supercritical toluene in presence of noble metal catalysts was written by Ghalandari, Vahab;Banivaheb, Soudeh;Peterson, Jessica;Smith, Hunter;Reza, M. Toufiq. And the article was included in AIChE Journal in 2022.Name: 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene This article mentions the following:
Solvothermal liquefaction (STL) is a thermochem. conversion method that uses sub-or supercritical solvents to convert waste plastics like waste polyurethane (PU) into value-added chems. This study aimed to evaluate catalytic STL utilizing toluene as a solvent for depolymerization of waste PU into valuable products. The effect of catalyst type (Pt/C, Pd/C, and Ru/C), catalyst loading (0-10 wt%), STL reaction temperature (330°C, 350°C, and 370°C), STL residence time (1, 3, and 5 h), and hydrogen loading (25, 50, and 75 bar) on STL conversion were studied. Result showed that Ru/C outperformed Pt/C and Pd/C and the STL conversion reached to as high as 87.2%. The concentrations of nitrogen-containing components like aniline and p-aminotoluene were increased with the increase of Ru/C loading and STL reaction temperature In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Name: 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene).
2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Name: 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene
