Mantelis, Charalampos A.Meyer, Thierry2009-02-092009-02-092009-02-09200810.1021/ie0712030https://infoscience.epfl.ch/handle/20.500.14299/34848WOS:000255871400007The heat flow reaction calorimetry technique was developed for reactions with supercrit. fluids and was applied to monitor the free-radical dispersion polymn. of Me methacrylate in supercrit. carbon dioxide (scCO2). The main math. equation for the calorimetric calcns. was modified to take into account the particularities linked to the supercrit. nature of the solvent. As a result, important heat transfer variables, such as the overall heat transfer coeff., can be measured at the actual reaction conditions. This information is later used to calc. the heat released by the reaction and thus monitor its evolution. The robustness and accuracy of the technique allowed also investigating the effects of several reaction parameters. Finally, the obtained data were used to illustrate the importance of pressure as far as the safety of the reaction is concerned.Polymerization (monitoring of free-radical dispersion polymn. of Me methacrylate in supercrit. carbon dioxide)CalorimetryHeat transferReactionSafetySupercritical fluids (supercrit. reaction calorimetry for measuring heat transfer properties and monitoring chem. reactions in supercrit. fluids)calorimetry heat transfer reaction supercrit fluidpolymn Me methacrylate supercrit carbon dioxide calorimetrySupercriticalcalorimetriefluidstext::journal::journal article::research article
