Porous silica microsphere scavengers |
摘要 |
Highly purified, porous silica microspheres contain functional groups which are capable of selectively binding to reaction impurities, such as excess reactant or reaction by-products, which are contained in a reaction medium. The reaction impurities can thereby be efficiently removed from the reaction medium, providing a convenient method for product purification.
