Abstract:
A process for reducing the residual olefin content of the alkylation reaction product of a single-ring aromatic hydrocarbon with an olefin having at least sixteen carbon atoms, said process comprising:(a) removing at least a portion of non-alkylated single-ring aromatic hydrocarbon from the alkylation reaction product to produce a remainder product having less non-alkylated single-ring aromatic hydrocarbon content; and(b) reacting said remainder product of step (a) at a pressure of about from 0 to 1 bar and at a temperature of about from 100.degree. to 250.degree. C. in the presence of an acidic catalyst selected from the group consisting of molecular sieves and clays, thereby producing a final alkylation reaction product having increased heavy alkylate content and reduced residual olefin content, and wherein said final alkylation reaction product is at least 82 weight % mono-alkylate.
