Process for producing monoalkenyl aromatic hydrocarbon compound. |
摘要 |
There is disclosed a process for producing a monoalkenyl aromatic hydrocarbon compound which comprises alkenylating a side chain of an aromatic hydrocarbon compound having at least one hydrogen atom bonded at alpha -position of the side chain (such as xylene) with a conjugated diene having 4 or 5 carbon atoms (such as butadiene) in the presence of a catalyst comprising the mixture obtained by heat treating metallic sodium together with an aluminum oxide containing a potassium compound in the atmosphere of an inert gas. According to the aforesaid process, an industrially useful monoalkenyl aromatic hydrocarbon compound can be produced in high yield at a low cost with enhanced safety from a specific aromatic hydrocarbon compound and a specific conjugated diene compound. |
