Abstract

Dialkylnaphthalenes are obtained by adding, with stirring, an olefin to a mixture of naphthalene, monoalkyl-naphthalene and sulphuric acid in an amount of 1.2-5.9 parts by weight per part of naphthalene while maintaining a temperature of 0 DEG C.-15 DEG C. and recovering dialkylnaphthalenes; monoalkylnaphthalenes are preferably recycled. The process is particularly applicable to one employing a nonene (C6-C12, containing at east 40% by volume of C9) fraction of a propylene polymer added in an amount of 1-3 mols per mol of naphthalene, the recycle of monononylnaphthalene amounting to 0.2-4 parts by weight per part of naphthalene.
