  • Patent number: 6303812
    Abstract: 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.

  • Patent number: 6118018
    Abstract: Disclosed is a method of adding 1 to 4 chlorine or bromine atoms to an aromatic ring of compound that has at least one electron-withdrawing groups on that ring. The aromatic compound is reacted with a chlorinating agent or a brominating agent in the presence of about 0.1 to about 10 mole % of a Lewis acid catalyst and about 0.001 to about 0.1 equivalents of an iodine-containing cocatalyst at a temperature of ambient to about 100.degree. C.

  • Patent number: 5977397
    Abstract: Disclosed is a method of removing an acid halide, anhydride, or ester impurity from a mixture with a desired product with which it codistills. At least about a stoichiometric amount of a primary or secondary amine having a boiling point at least 10.degree. C. higher or lower than the boiling point of said desired product is added to the mixture. The desired product is not an acid halide, anhydride, or ester and does not react with the amine. The amine forms a reaction product with the impurity that has a boiling point at least 10.degree. C. higher or lower than the boiling point of the desired product. The mixture is distilled to isolate the desired product.
