International Classification:

C07C 307/00

US Classification:

508561, 564305

Abstract:

Disclosed herein is a post-treated salt of a sulfurized alkyl-substituted hydroxyaromatic composition which is a reaction product of (a) a salt of a sulfurized alkyl-substituted hydroxyaromatic composition, wherein the alkyl-substituted hydroxyaromatic compound is derived from alkylation of a hydroxyaromatic compound with one or more olefins comprising Cto Coligomers of monomers selected from propylene, butylene or mixtures thereof, (b) a source of an aldehyde and (c) a primary and/or secondary monoamine compound having at least one active hydrogen. The post-treated salt of a sulfurized alkylhydroxyaromatic composition disclosed herein has a reduced content of unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt as compared to the content, by combined mass, of the unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt present in the non-post-treated salt of a sulfurized alkyl-substituted hydroxyaromatic composition.

International Classification:

C09K 8/584
C10M 145/02
C10M 149/02

Abstract:

The present disclosure provides a method of treating a hydrocarbon-containing reservoir. The method involves introducing into the reservoir a surfactant composition. The surfactant composition includes an alpha olefin sulfonate or an isomerized olefin sulfonate. The alpha olefin sulfonate or the isomerized olefin sulfonate is synthesized by i) oligomerizing a monomer comprising a Cto Cmono-olefin to form an oligomerization product and ii) sulfonating the oligomerization product.
