Exploiting carbon dioxide as co-monomer with epoxides in the production of polycarbonates is economically highly attractive. More effective catalysts for this reaction are intensively being sought. To promote better understanding of the catalytic pathways, this study uses density functional theory calculations to elucidate the reaction step of CO2 insertion into cobalt(III)-alkoxide bonds, whic...

In this paper we study a self-adaptive predictive functional control algorithm as an approach to the control of the temperature in an exothermic atch reactor. The batch reactor is located in a pharmaceutical company in Slovenia and is used in the production of medicines. Due to mixed discrete nd continuous inputs the reactor is considered as a hybrid system. The model of the reactor used for th...

We demonstrate the emergence of spontaneous temperature regulation by the combined action of two sets of dissipative structures. Our model system comprised an incompressible, non-isothermal fluid in which two sets of Gray-Scott reaction diffusion systems were embedded. We show that with a temperature dependent rate constant, self-reproducing spot patterns are extremely sensitive to temperature ...

The polymerization of resin adhesives, which is highly nonlinear, is chosen as a control process in this paper. When phenol and formaldehyde are mixed, a sudden and unpredictable heat is produced due to an exothermic reaction, which could cause the deviation of process temperature and hence diminish the product quality. Therefore, temperature control is necessitated for exothermic batch reactor...

ALL modern volatile anesthetics produce carbon monoxide in strongly exothermic reactions with anhydrous carbon dioxide absorbents. Although desflurane produces the most carbon monoxide, the reaction with sevoflurane produces the most heat. Using real anesthesia machines, sevoflurane, and desiccated Baralyme® (Allied Healthcare Products, Inc., St. Louis, MO), peak absorbent canister temperatures...
