Patent number: 6670513Abstract: An alkylated hydroxyl-containing aromatic compound is produced by isomerizing a normal alpha-olefin having from about 16 to about 30 carbon atoms in the presence of a first solid, acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefin, then alkylating an hydroxyl-containing aromatic compound with the mixture of isomerized olefins in the presence of a second solid, acidic catalyst. The first solid, acidic catalyst can be SM-3, MAPO-11, SAPO-11, SSZ-32, ZSM-23, MAPO-39, SAPO-39, ZSM-22, SSZ-20, ZSM-35, SUZ-4, NU-23, NU-87, natural ferrierite or synthetic ferrierite.

Patent number: 6479440Abstract: An alkaline earth alkylaryl sulfonate having a BN of at least 250, wherein the aryl radical is not phenol, wherein the alkyl chain is a linear chain that contains between 14 and 40 carbon atoms, and wherein the mole % of the aryl-sulfonate radical fixed on position 1 or 2 of the linear alkyl chain is between 13% and 30%. Such an alkaline earth alkylaryl sulfonate has improved compatibility, solubility, and foaming performances while having low color and no skin formation. The starting alkylate has a low iodine number, a very high level of monoalkylate, and, as a consequence, a high yield at the sulfonation step.Type: GrantFiled: January 25, 2001Date of Patent: November 12, 2002Assignee: Chevron Oronite S.
