Important process parameters were tested covering a wide range of operating conditions: reaction temperature (80-135 °C), benzene to nitric acid molar feed ratio (0.96-1.15) and stirring speed (390-1700 rpm). The residence time and the sulphuric acid strength were fixed at 2 min and 68%, respectively. The data from a large number of experiments show a good agreement with the results of a mathematical model of the reactor. | URI: | https://hdl.handle.net/10316/3804 | DOI: | 10.1016/j.cej.2004.12.022 | Direitos: | openAccess |
