| titleOfInvention |
Alkylation of aromatics with removal of polymeric byproducts |
| abstract |
Detergent-quality linear alkylaromatics are recovered from an alkylation reactor effluent containing polymeric byproducts, such as dimers and trimers of the olefinic feedstock. The effluent stream passes to another reactor operating at a higher temperature than the first reactor. Heavy alkylate is separated from the detergent-quality linear alkylaromatics by conventional separation methods such as distillation. This invention decreases the concentration of polymeric byproducts in the linear alkylaromatics. The benefits of this invention include a higher linearity and/or a lower bromine index in the detergent-quality linear alkylaromatic product, as well as a lower color after sulfonation of the linear alkylbenzene sulfonate. |
