The Carbon2Polymer project involves a multistep reaction sequence for the non‐phosgene synthesis of the high‐value polymer precursor toluene‐2,4‐diisocyanate (TDI) starting from carbon dioxide. The present study of the oxidative carbonylation revealed that for the intermediate toluene‐2,4‐dicarbamate (TDC) the productivity is highest with Pd@ZrO2, followed by Pd@CeO2. As one of the side products which...
CO2 was investigated as carbon source for the synthesis of the polymer precursor toluene‐2,4‐diisocyanate (TDI). A four‐step synthesis was envisaged. The first step, i.e., the Ru‐catalyzed CO2 hydrogenation to [HCOOH·amine] adducts, was carried out under biphasic conditions allowing for straightforward reutilization of the catalyst phase. The investigation of the second step, the esterification of...
Promising strategies to use supercritical CO2 (scCO2)for catalyst immobilisation can be developed on the basis of its unique and tunable solubility propertiesin the vicinity of, and especially just beyond, the critical data of pure carbon dioxide. The present chapterdescribes briefly the background and experimental details of four different methods. In the first case,scCO2 is used as a “switch” to...
