Abstract: Method of making an electroplated interconnection wire of a composite of metal and carbon nanotubes is disclosed, including electroplating a substrate having a conductive baseline on a surface thereof in an electroplating bath containing a metal ion and carbon nanotubes, so that an electroplated interconnection wire of a composite of the metal and carbon nanotubes is formed on the conductive baseline. Alternatively, a method of the present invention includes preparing a dispersion of carbon nanotubes dispersed in an organic solvent, printing a baseline with the dispersion on a surface of a substrate, evaporating the organic solvent to obtain a conductive baseline, and electroplating the surface in an electroplating bath containing a metal ion, so that an electroplated interconnection wire of a composite of the metal and carbon nanotubes is formed on the conductive baseline.

Abstract: The present invention relates to a process for preparing pyromellitic dianhydride via an oxidation in gas phase under normal pressure. The process is characterized in that a catalyst system is used, which catalyst system comprises a catalyst which is a mixture of vanadium and tungsten oxides; a catalyst support comprising rutile and at least one material selected from the group consisting of tungsten carbide, silicon carbide and a mixture thereof; and a cocatalyst comprising oxides of manganese, antimony, bismuth, phosphorus, copper, aluminum, titanium or a mixture thereof, an oxide of an element of the VIIIB group of the periodic table, and an oxide of an alkali metal and/or alkaline earth metal. In this process, pyromellitic dianhydride is produced from a feedstream containing 1,2,4,5-tetraalkylbenzene in a gas flow rate of 4,000.about.12,000 hr.sup.-1 via a selective oxidation at 300.about.450.degree. C. in the presence of air which acts as an oxidant.
