Document Type and Number:
Japanese Patent JP2656641
Kind Code:
B2
Abstract:
The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6-diisopropylnaphthalene isomer is obtained in the presence of an acidic crystalline molecular sieve catalyst having twelve membered oxygen rings. The catalyst pore aperture dimension ranges from 5.5 ANGSTROM to 7.0 ANGSTROM . The use of these shape selective catalysts results in a diisopropylnaphthalene stream which is enhanced in beta isomers and enhanced in the desired 2,6-diisopropylnaphthalene isomer. A particularly preferred catalyst is synthetic Mordenite. Specific catalyst modifications are also described to improve selectivity to the desired 2,6-diisopropylnaphthalene isomer.
