Processes and Apparatus for Making Detergent Range Alkylbenzenes Using Transalkylation |
摘要 |
Dialkylbenzenes are transalkylated in the presence of benzene and solid catalyst. The transalkylation product is subjected to distillation to provide a lower-boiling, benzene-containing fraction which is fed to a transalkylation reactor as at least a portion of the benzene. Thus, high benzene to dialkylbenzene molar ratios can be economically maintained in order to enhance catalyst stability.
