  • Process for production of alkyl aromatics
    Patent number: 4691068
    Abstract: An improved process for producing a mono alkyl aromatic by reacting a mono nuclear aromatic compound and an alkylating agent under alkylation conditions to produce the reaction product comprising unreacted mono nuclear aromatic compound, alkane, mono alkyl aromatic, dialkyl aromatic and by-products, treating the reaction product to remove unreacted mono nuclear aromatic compound, free paraffin, and produce a crude product stream containing mono alkyl aromatic, dialkyl aromatic and by-products, separating the majority of the mono alkyl aromatic from the crude product stream to produce a higher boiling fraction containing a minor amount of mono alkyl aromatic, dialkyl aromatic and by-products, and separating the higher boiling fraction into a recycle stream containing mono alkyl aromatic and a by-product stream substantially free of mono alkyl aromatic, and introducing the recycle stream into the alkylation reaction.
