Abstract: Lamination of a tufted, primary carpet backing to a secondary backing is conducted using a composite hot melt adhesive in sheet form. The composite adhesive overcomes the unfavorable temperature-viscosity gradient within the carpet structure during the lamination process, yielding tufted pile carpets with good tuft encapsulation, tuft bind strength and delamination strength. Also disclosed are hot melt adhesive compositions suitable for use in sheet form in such a process.

Abstract: Para selectivity in the conversion of a monosubstituted benzene containing a meta-directing group to disubstituted benzenes can be substantially enhanced by carrying out the reaction in the gas phase with an inorganic or organic substitution agent in the presence of a catalyst composition comprising a crystalline molecular sieve material. In particular, nitrobenzene can be converted using nitrogen dioxide in the gas phase to a product containing an augmented proportion of para-dinitrobenzene using a wide range of catalyst compositions comprising both synthetic and naturally occurring crystalline molecular sieve materials such as ferrierites, X-type zeolites, Y-type zeolites, silicalite, framework-modified silicalites, ZSM aluminosilicates, AMS-1B borosilicates, and AlPO.sub.4 types.
