A heavy mono-alkylated benzene, having a heavy-alkylate content of at least 20 weight percent, is produced by reacting a heavy mono-alkylated benzene with an olefin, having from 6 to 14 carbon atoms, at a pressure of up to about 10 bars and a temperature of about from 100° to 225° C in the presence of an acidic catalyst. The acidic catalyst can be a molecular sieve or clay. The molecular sieve can be a natural or synthetic zeolite.
On produit un benzène monoalkylé lourd, ayant une teneur en alkylat lourd d'au moins 20 % en poids, en faisant réagir un benzène monoalkylé lourd avec une oléfine en C6-C14, à une pression allant jusqu'à 10 bars et à une température allant d'environ 100 à 225 .degré.C, en présence d'un catalyseur acide. Le catalyseur acide peut être un tamis moléculaire ou une argile. Le tamis moléculaire peut être une zéolite naturelle ou synthétique.
