Abstract: The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6diisopropylnaphthalene 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.ANG. to 7.0.ANG.. 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.

Abstract: 2077550 9113681 PCTABS00007 The present invention provides a process for the preparation of acidic aqueous solutions consisting essentially of phosphomolybdovanadate salts. Certain processes of the present invention dissolve in water an oxide, oxoacid, or mixtures thereof, and at least one oxoanion salt of phosphorus, molybdenum, and vanadium, wherein the sum of salt cationic charges does not exceed the sum of the phosphomolybdovanadate anionic charges in the solution. Other processes of the present invention dissolve in water a) an oxide, oxoacid, oxoanion salt, or mixtures thereof of phosphorus, molybdenum, and vanadium and b) a carbonate salt, bicarbonate salt, hydroxide salt or mixtures thereof, wherein the sum of salt cationic charges does not exceed the sum of the phosphomolybdovanadate anionic charges in the solution. The present invention also provides processes for the preparation of solid phosphomolybdovanadate salts by evaporating the so produced aqueous solutions to recover essentially all the dissolved phosphomolybdovanadate salt in solid form.
