Latest Patents
One of her latest patents is focused on an acrylate-based adsorbent resin for the immobilization of enzymes. This invention involves the immobilization of enzymes on macroporous hydrophilic polymer beads through adsorption. The polymer beads are made from cross-linked, acrylate-based resins that contain pendant hydroxy groups. The composition of these resins includes 10-70% methyl methacrylate, 10-70% methylacrylate, 5-14% ethylenically unsaturated monomer with at least one pendant hydroxyl group, and 10-25% divinylbenzene. These resins provide immobilized enzyme preparations that exhibit excellent physical strength, stability, and high enzyme activity.
Another notable patent involves a process for the preparation of halohydroxyalkyl carbamates and 2,3-epoxyalkyl carbamates. This process entails contacting an epihalohydrin carbonate with a secondary amine-containing compound. The secondary amine is selected based on its pKa, ensuring it reacts with the epihalohydrin carbonate without catalyzing unwanted by-products. The process is conducted in a polar organic solvent, leading to the formation of halohydroxyalkyl carbamates. Additionally, the invention includes a step for converting these carbamates into 2,3-epoxyalkyl carbamates using an ion-exchange resin.
