Latest Patents
One of Schisla's latest patents is titled "Process for the extraction of material from multi-phase systems." This innovative method involves adding a first fluid and an extraction fluid to a vessel, creating a two-phase two-layer system. The process allows for the extraction and separation of components from fluids while maintaining the integrity of the discrete layers. The agitation of the two-phase system facilitates the communication between the fluids, resulting in the extraction of components into the extraction fluid. After agitation, the first fluid can be recovered with reduced extractive components.
Another significant patent by Schisla is focused on "Enhanced hydrogenation catalyst removal from block copolymers by reduction in polymer cement viscosity by increasing the vinyl content of the block copolymers." This process improves the production of hydrogenated block copolymers by anionically polymerizing monomers in an inert hydrocarbon solvent. The innovation lies in reducing the viscosity of the polymer cement, which enhances the removal of hydrogenation catalyst residue, thereby improving the overall efficiency of the process.
