| titleOfInvention | Process for preparation of n-propyl benzene |
| abstract | Disclosed is a process for preparation of n-propyl benzene. The process gives high selectivity and yield of n-propyl benzene by single step catalytic alkylation that involves contacting a mixture of aromatic hydrocarbon having an active hydrogen on a saturated α-carbon, such as toluene, and an alkene, such as ethylene, in presence of a metal catalyst, a solid support, and an initiator. Following the alkylation, aqueous and organic phases are separated from a reaction mixture. The aqueous phase is separated for recovery of the catalyst, the solid support, and un-reacted aromatic hydrocarbon (e.g., toluene); and the organic phase is separated for obtaining n-propyl benzene and byproduct. Thus, the catalyst phase can be recovered and recycled in the next alkylation reaction. Also, the process facilitates recovery and recycling of the byproduct for the better selectivity. |
