- W3004384759 abstract "Transition from batch to continuous processing promises strong improvements via reduced energy demand, resource consumption, waste production, and physical footprint of the plant — so-called “process intensification”. This transition has been already demonstrated in the pharmaceutical industry but is largely lacking to-date for the—much larger scale—specialty chemicals industry. A critical step in this transition is the acquisition of robust and accurate reaction kinetics, which are typically poorly understood (if known at all) for conventional batch processes.In this work, a detailed kinetic investigation of the kinetics for succinimide dispersants production via amination of polymeric anhydrides was conducted in a small laboratory-scale batch reactor using online IR spectroscopy as the analytical tool. The use of a small batch system enables the acquisition of large amounts of data through measurement of long concentration time traces, thus facilitating the acquisition of robust kinetics. MATLAB was used to fit the experimental data and deduce robust reaction kinetics. We found that the reaction kinetics could be described by a two-step mechanism, and that the kinetics of each reaction step could be determined separately in different temperature windows. In this way, we were able to obtain the first robust reaction kinetics for this reaction system. This work can be further applied to simulate the kinetics for a family of related lubricant chemistries by varying feed and operating conditions (temperature, feed ratio, etc.) and thus provides a strong support for the design of a continuous processing system." @default.
