Title: Yumin Sun: Innovator in Selenium Technology
Introduction
Yumin Sun is a notable inventor based in Tianjin, China. He has made significant contributions to the field of selenium technology, particularly through his innovative patent related to esterified selenium polysaccharides. His work aims to enhance the immunity of organisms by increasing selenium content in the blood.
Latest Patents
Yumin Sun holds a patent for an "Esterified selenium polysaccharide and preparation method and use therefor." This patent outlines a preparation method that involves several steps. The process begins with the dropwise addition of O-SeCl to a triethylamine-containing D-galactose allyl glucoside solution, which is then reacted at room temperature. This reaction yields 3,4-oxo-cyclo selenite galactose allyl glucoside. Following this, NaHCO is mixed into a polysaccharide solution, and acryloyl chloride is added dropwise while maintaining a temperature not exceeding 40°C. The final step involves a displacement reaction of the acrylated polysaccharide with the 3,4-oxo-cyclo selenite galactose allyl glucoside under the action of a Ru catalyst, resulting in the formation of the esterified selenium polysaccharide. This innovative compound has been shown to improve the immunity of tested organisms.
