The present invention provides sulfur- or selenium-containing compounds comprising hydrophobic moieties and ethoxylated ester or ethoxylated amide moieties such that the compounds have surfactant properties. Also provided are methods for using the disclosed compounds or mixtures thereof in a variety of applications.

Ethoxylated surfactants

The present invention provides sulfoxide compounds comprising hydrophobic ester or amide moieties such that the compounds have surfactant properties. Also provided are methods for using the sulfoxide compounds or mixtures of the sulfoxide compounds in a variety of applications.

Sulfoxide-based surfactants

Provided herein are processes for the preparation of N-acylated amines. In particular, the processes comprise contacting an amine with an acid comprising a carboxylic acid group to form the N-acylated amine.

N-acylation of amines

Provided herein are processes for the production of methionine or selenomethionine from homoserine. In particular, the processes proceed via the production of 4-substituted 2-aminobutanoic acid intermediates or derivatives thereof.

Preparation of methionine or selenomethionine from homoserine via a 4-substituted 2-aminobutanoic acid intermediate

Provided herein are processes for the production of methionine or selenomethionine from homoserine. In particular, the processes proceed via the production of carbamate intermediates.
