Introduction
Hans J. Rommerskirchen, an accomplished inventor based in Düsseldorf-Eller, Germany, has made significant contributions to the field of surfactants through his inventive prowess. With a portfolio that boasts six patents, he has played a vital role in advancing chemical processes, particularly in the realm of fatty acid alkyl esters and surfactant formulations.
Latest Patents
Among Rommerskirchen's latest patents is a noteworthy innovation focused on the "Control of disalt in α-sulfofatty acid ester surfactants." This invention addresses the production of light-colored surfactants derived from the sulfonation of fatty acid alkyl esters. His methodology involves sulfonating these esters with less than two moles of SO₃ per mole of fatty acid alkyl ester, followed by a specialized work-up process in an aqueous medium. The invention emphasizes the regulation and reduction of α-sulfofatty acid disalts by transesterifying the sulfonation product before treatment with an aqueous medium, utilizing approximately 0.5 mole equivalent of an alcohol based on the SO₃, which is not intended for α-sulfonation. This innovative approach significantly enhances the quality of the resulting surfactants, showcasing Rommerskirchen's commitment to improving industrial chemical processes.
