Abstract

Sulfonic acids serve as important molecules in organic chemistry. For example, the sulfonic group, in either its acidic or salt form, is capable of solubilizing substances in water thus increasing their usefulness especially in the organic dye industry. 1 These acids are also frequently used as catalysts in organic chemistry, for instance, in esterification of amino acids and peptides. 2 and 3 Most aliphatic sulfonic acids are made by oxidation of thiols, 4 while aromatic ...
