Latest Patents

One of Zudkevitch's latest patents pertains to the extraction and/or extractive distillation of ethanol from aqueous mixtures. This innovative method involves concentrating ethanol from ethanol-water mixtures using a cyclic ketone or cyclic alcohol solvent, specifically targeting compounds with at least seven or eight carbons, respectively. The process uniquely allows for the production of a first overhead that can be steam with minimal ethanol content and a second overhead that yields essentially pure ethanol. Importantly, the preferred solvents are non-toxic, enabling the derived alcohol to be safe for human consumption.

Another significant patent addresses the separation of low molecular weight alcohols, particularly ethanol, from aqueous mixtures. This process employs extraction and extractive distillation techniques, utilizing specific solvents, such as phenols with at least six carbon atoms that boil between 180°C and 350°C. This innovative approach ensures the efficient separation of ethanol from its aqueous counterparts.
