Abstract:
A process for producing alkylated, hydroxyl-containing aromatic compounds, said process containing:(a) isomerizing a normal alpha-olefin or mixture of normal alpha-olefins having from about 16 to about 30 carbon atoms in the presence of a first acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefins wherein at least about 70% of the isomerized olefins are branched-chain olefins; (b) alkylating a hydroxyl-containing aromatic compound with said mixture of isomerized olefins in the presence of a second acidic catalyst comprising a sulfonic acid resin catalyst or acidic clay to thereby provide an alkylated hydroxyl containing aromatic compound having at least 82% of the para isomer.
