Intermolecular compounds of amino acids and sulfoxides and method of preparing same

An intermolecular compound of an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble. A method which comprises reacting an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble. A method for recovering an amino acid containing a sulfonic acid group and a carboxylic acid group from an admixture of the amino acid with other ingredients by adding thereto a sulfoxide in which the amino acid is moderately soluble, with the sulfoxide being added in a sufficient amount to solubilize the amino acid, separating an intermolecular compound of the amino acid with the sulfoxide, and then recovering the amino acid from its intermolecular compound. A method for forming an intermolecular compound of a sulfoxide with an amino acid containing a sulfonic acid group and a carboxylic acid group by contacting the amino acid with a solvent which contains the sulfoxide dissolved therein with the solvent having a low polarity and the amino acid reactant and intermolecular compound having a low solubility in the solvent. This method also provides a means for removing a sulfoxide from a solvent in which it is dissolved.
