Title: The Innovations of Gerardo Carrillo: Pioneering Processes in Sulfonic Acid Separation
Introduction: Gerardo Carrillo, an inventive mind based in San Donato Milanese, Italy, has made significant contributions to the field of chemistry through his innovative processes. With two patents to his name, Carrillo focuses on methods that enhance the separation and extraction of sulfuric acid and paraffins from complex mixtures, showcasing his expertise in chemical engineering.
Latest Patents: Carrillo’s latest patents demonstrate his commitment to developing efficient methods for chemical processing. The first patent, titled "Process for the separation of sulfuric acid from aqueous mixtures of paraffin-sulfonic acids," outlines a procedure to remove excess sulfuric acid from a mixture of paraffin-sulfonic acids. This method involves mixing the paraffin-sulfonic acid mixture with one or more halogenated solvents, resulting in a two-phase mixture where the organic phase contains dissolved paraffin-sulfonic acids and the aqueous phase contains sulfuric acid. The separation of these phases allows for the subsequent evaporation of halogenated solvents and the concentration of paraffin-sulfonic acids.
The second patent focuses on "Process for extracting paraffins from their mixtures with alkanesulfonic." This innovative technique involves using ultraviolet radiation to initiate sulfoxidation of n-paraffins, leading to a mixture where unconverted n-paraffins can phase separate. The remaining mixture is then treated with alcohols, such as isopropanol, to form a two-phase mixture, which is extracted using supercritical carbon dioxide to recycle n-paraffins back into the sulfoxidation process, resulting in a paraffin-free product suitable for further alkane-sulfonate production.
Career Highlights: Throughout his career, Gerardo Carrillo has held positions at notable companies, including Enichem Augusta S.p.a. and EniRicerche S.p.a. His work at these organizations has significantly influenced advancements in chemical processing and patent development, further establishing him as a respected inventor in the field.
Collaborations: Collaboration has been a key component of Carrillo's work, with notable collaborators including Cosimo Franco and Lucio Faggian.
