<p>The present invention relates to a process for the alkylation of an aromatic substrate and to a process for the transalkylation of polyalkylated aromatic components, wherein the nitrogen containing compounds impurities in the aromatic substrate feedstock and/or the alkylating agent feedstock are monitored in a range 15 wppb-35 wppm by dry colorimetry. In an advantageous embodiment of the alkylation process the aromatic substrate is benzene and the alkylating agent in ethylene. In an advantageous embodiment of the transalkylation process the aromatic substrate is benzene and the polyalkylated aromatic component is diethylbenzene.</p> |
