    • A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone. The operating conditions, e.g. temperature and pressure, of the first alkylation reaction zone are controlled effective to cause the alkylatable aromatic compound to be partly in the vapor phase and partly in the liquid phase, and the ratio of the volume of liquid to the volume of vapor of the feed in each zone to be from about 0.1 to about 10. The aromatic compound and the alkene of the feed are reacted in the presence of the alkylation catalyst to form an effluent comprising the alkylaromatic compound, unreacted alkylatable aromatic compound, any unreacted alkene and the alkane. The effluent is withdrawn from the first alkylation reaction zone and then supplied to the second alkylation reaction zone without removal of the alkane.

    • A process for co-production of an alkenyl aromatic compound such as, for example, styrene and t-butylstyrene, and an oxygenated sulfur-containing compound such as, for example, a sulfoxide or a sulfone is disclosed which comprises: (1) contacting, in the presence or absence of a catalyst, an .alpha.-methyl benzylic hydroperoxide with an organic sulfide compound to produce a mixture of an .alpha.-methyl benzylic hydroxide and an oxygenated sulfur-containing compound; (2) separating the .alpha.-methyl benzylic hydroxide from the sulfur-containing compound; (3) contacting the .alpha.-methyl benzylic hydroxide with a base to convert the .alpha.-methyl benzylic hydroxide to the alkenyl aromatic compound; and optionally, (4) recovering the alkenyl aromatic compound from the oxygenated sulfur-containing compound. The sulfoxide produced can be oxidized to a sulfone. The contacting of the .alpha.-methyl benzylic hydroxide with a base can also be carried out before the .alpha.-methyl benzylic hydroxide is separated from the oxygenated sulfur-containing compound followed by separation of the sulfur-containing compound.
