Beschreibung
Zusammenfassung:The current invention is providing a process for the production of, optionally functionalized, styrene monomers comprising the steps of (a) feeding benzene or aromatic oxygenate and ethylene, as well as a heterogeneous catalyst into a reactor forming a mixture of benzene or aromatic oxygenate and ethylene (the starting material), and (b) heating said mixture and applying pressure to obtain crude styrene, preferably at a pressure (of ethylene) in step (b) of between and including 10 bar and 70 bar; and at a temperature ranging from and including 150°C to 250 °C. Further the invention is aimed at the use of a heterogeneous catalyst for the production of, optionally functionalized, styrene from benzene or aromatic oxygenate with ethylene.
