Abstract

A method for making a surfactant-based monolithic column is provided. The method comprises providing a mixture comprising at least one surfactant monomer, at least one crosslinker, at least one initiator, and at least one porogen and polymerizing the mixture to form the surfactant-based monolithic column. The present disclosure also provides a surfactant-based monolithic column, a method for separating molecules, and a process for preparing a surfactant monomer.

Claims (8)

1. A process for preparing a surfactant monomer, the process comprising:

providing a carboxylic acid having a carbon chain length ranging from about 6 to about 20 and a tail group, wherein the tail group comprises NH 2 , or OH;

reacting the carboxylic acid with aryloyl chloride to form a first product;

reacting the first product with 1-hydroxypyrrolidine-2,5-dione to form a second product; and

reacting the second product with an amino acid to form the surfactant monomer including an amino acid functional group.

2. The process of claim 1 , wherein the amino acid valine, nor-valine, leucine, isoleucine, tert-leucine, nor-leucine, aspartic acid, glutamic acid, arginine, histidine, tryptophan, tyrosine, cysteine, threonine, serine, proline, or glycine.

3. The process of claim 1 , wherein the surfactant monomer is polymerizable.

4. The process of claim 3 , wherein the surfactant monomer is polymerized to 10-acrylamido decenoxy carbonyl- L -leucinate.
