  • Process for producing alkylaromatics
    Patent number: 3931350
    Abstract: In a process for producing alkylaromatics by halogenating a paraffin and reacting the halogenated paraffin with an aromatic hydrocarbon, the rate of halogenation is improved by treating the n-paraffin to selectively remove oxygen-containing hydrocarbonaceous compounds from the n-paraffin with a sorbent selective for such oxygen-containing compounds, and subsequently halogenating the treated n-parffin. The improvement is particularly useful in producing alkylaromatic hydrocarbons from monocyclic aromatic compounds and n-paraffins.
