  • Patent number: 5446227
    Abstract: 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.
