Latest Patents

Umekawa holds a patent for a medical adsorbent and the process for its production. This medical adsorbent is designed to produce minimal side effects, such as constipation, while exhibiting excellent adsorption for ionic organic compounds, including those that cause uremia. The adsorbent is engineered to perform adequately at low doses and avoids the adsorption of high-molecular compounds that are essential for the body, such as enzymes and polysaccharides. The production process involves carbonizing a spherical phenol resin in a nitrogen atmosphere at temperatures ranging from 400 to 1000°C, activating the carbonized resin at 800 to 1000°C, and treating it with dilute hydrochloric acid. The final product has an area to weight ratio of 500-2000 m/g, a pore volume of 0.2-1.0 mL/g, and a packing density of 0.5-0.75 g/mL.
