Abstract
This invention is directed to an improvement in the process for the production of alkylaromatic compounds that results in lower levels of residual unreacted materials in the final product. This invention comprises: 1) alkylation of an aromatic compound with an alkylating agent and a catalyst to produce an effluent stream comprising an alkylaromatic compound and unreacted materials; 2) heating the effluent stream; 3) stripping the effluent stream in a stripping device in the presence of steam; 4) separating a stripping stream from the stripping device, the stripping stream rich in unreacted materials; and 5) separating a product stream from the stripping device, the product stream rich in alkylated aromatic compound.
