Latest Patents

One of Rashmi's latest patents involves the treatment of aqueous systems using a chemically modified tannin. This composition comprises tannin containing hydroxyl groups that have been chemically modified through reactions with esterification and etherification agents. The resulting chemically modified tannin is derivatized to enhance its properties, making it water-soluble or dispersible at a pH below 7 and water-insoluble at a pH above 7. This innovation is particularly useful for coagulating and detackifying solid particles suspended in aqueous systems, such as paint particles in wastewater from paint spray booth operations. Additionally, these modified tannins have applications in demulsifying oil-in-water emulsions.
