Latest Patents

Yanhui Yi holds a patent for an "Alkali metal ion modified titanium silicalite zeolite for gas phase epoxidation of propylene and hydrogen peroxide and preparation method thereof." This invention involves a method that includes several steps: preparing an alkali metal hydroxide modification solution, conducting controlled hydrothermal treatment on a TS-1 zeolite matrix, and performing post-treatment on the hydrothermally modified TS-1 zeolite. The washing process is particularly noteworthy, as it involves using a low concentration alkali metal hydroxide solution to reserve alkali metal ions on the silicon hydroxyl of the modified titanium silicalite zeolite. The infrared characteristic absorption band of the framework titanium active center modified by the alkali metal ions is found in a range above 960 cm and below 980 cm.
