摘要： Disclosed is a method of halogenating the ring of an aromatic compound. The aromatic compound is contacted with a halogenating agent in the presence of a heterogeneous catalyst. The catalyst is the calcination reaction product of: (A) 51 to 99 wt % of a support which comprises at least one inorganic oxide or hydroxide of at least one metal that is at least divalent and forms a metal-to-oxygen matrix during calcination; and (B) 1 to 49 wt % of at least one dopant which comprises a compound that places an element that is at least divalent, bonded to oxygen atoms, into said matrix during said calcination, resulting in the formation of an acidic solid.

摘要： Disclosed is a method of making a mercaptan by reacting hydrogen sulfide with an olefin in the presence of a heterogeneous acidic catalyst. The catalyst can be made by calcining a mixture of a hydroxide, such as Zr(OH).sub.4 or Ti(OH).sub.4, with an acidic site donor, such as H.sub.2 SO.sub.4, (NH.sub.4).sub.2 SO.sub.4, or WO.sub.3.

摘要： Disclosed is a method of isolating the aromatic product formed when a substrate having the general formula is dehalogenated, forming a product mixture of copper salts and aromatic product, where X is the halogen removed from the substrate to form the aromatic product, R′ is COOH, COOR, COR, CN, COH(R)2, or SO3H, each R″ is independently selected from halogen, R, or OR or two vicinal R″ groups form one or more fused aromatic rings, R is alkyl from C1 to C18 or aryl from C6 to C18, and n is 1 to 4. Water in an amount about 1 to about 5 times the amount of the substrate is added to the product mixture, forming an organic phase that contains the aromatic product and an aqueous phase that contains the copper salts. If the density of the organic phase differs from the density of said aqueous phase by less than 0.1 g/cc, a suitable solvent is added to the product mixture in an amount sufficient to increase the differences between the organic and aqueous phases to at least 0.1 g/cc. The organic phase can be separated from the aqueous phase by decantation.
