A circulating fluidized reactor of polyethylene was modeled with the proper hydrodynamics for a riser and downer and combined with a kinetic model based on the moment equations. The hydrodynamic model was able to predict the profiles of the following parameters through the riser and downer: cluster velocity, bed porosity, concentration of potential active sites, active sites, gas-phase components, molecular weights, and reactor temperature. It was shown that one could control the monomer consumption and molecular weight, which are crucial in the reactor behavior and production properties, respectively, by setting different operating hydrodynamic conditions, such as the gas velocity in the riser and the solid circulation rate.

An sp3 C–H bond-transformation reaction of toluene substrates to afford the corresponding allylbenzene derivatives is described. Optimum conditions were identified as involving the use of tetrabutylammonium iodide and tert-butyl hydroperoxide at 80 °C.
