Abstract

Official abstract text for this publication.

The present invention is directed to an isomerized alpha olefin sulfonate and a method of making the same wherein the isomerized alpha olefin sulfonate is derived from sulfonating an isomerized alpha olefin with sulfur trioxide in the presence of air thereby producing an isomerized alpha olefin sulfonic acid, wherein the isomerized alpha olefin is derived from the isomerization of C 12 -C 20 normal alpha olefins; and neutralizing the isomerized alpha olefin sulfonic acid with a source of an alkali metal or ammonium or substituted ammonium ion.

First claim

Opening claim text (preview).

What is claimed is: 1. A skeletal isomerized alpha olefin sulfonate having the general formula: R—SO 3 M wherein R is an aliphatic hydrocarbyl group containing one or more olefin or alcohol moieties or mixtures thereof derived from a skeletal isomerized alpha olefin having a Branching Index (BI) from about 10 to about 30, a Branching Proximity (BP) from about 5 to about 36 and a Free Carbon Index (FCI) from about 1 to about 10 and having from about 12 to about 20 carbon atoms; and wherein M is a mono-covalent cation. 2. The sulfonate of claim 1 wherein the aliphatic hydrocarbyl group is derived from a skeletal isomerized alpha olefin having a Branching Index (BI) from about 16 to about 27, a Branching Proximity (BP) from about 9 to about 34 and a Free Carbon Index (FCI) from about 2 to about 8. 3. The sulfonate of claim 1 wherein M is an alkali metal or ammonium or substituted ammonium ion. 4. The sulfonate of claim 1 wherein M is sodium. 5. The sulfonate of claim 1 wherein the skeletal isomerized alpha olefin aliphatic is derived from the skeletal isomerization of C 10 to C 20 normal alpha olefins. 6. The sulfonate of claim 1 wherein the skeletal isomerized alpha olefin aliphatic is derived from the skeletal isomerization of C 12 to C 18 normal alpha olefins. 7. The sulfonate of claim 1 wherein the skeletal isomerized alpha olefin aliphatic is derived from the skeletal isomerization of C 16 to C 18 normal alpha olefins.
