Title:
IMPROVED METHOD OF INCREASING BETAAISOMER CONTAINING PERCENTAGE BY ISOMERIZATION OF ALPHAA AND BETAAISOPROPYLNAPHTHALENE MIXTURE
Document Type and Number:
Japanese Patent JPS5350145
Kind Code:
A
Abstract:
A process for treating mixtures of isopropylnaphthalenes (IPN) obtained from any source and increasing the beta-isopropylnaphthalene content thereof by a batch or continuous isomerization reaction in the presence of a rare earth metal ammonium-exchanged, "Y Type" crystalline aluminosilicate catalyst. The process also includes disproportionation of higher alkylates of naphthalene, such as diisopropylnaphthalene, to increase the IPN content of said mixtures.
