Purification and Metal Scavenging

ISOLUTE® Si-Trisamine is a silica bound equivalent of a Trisamine base and can scavenge a variety of electrophiles, including aldehydes, acid chlorides, sulfonyl chlorides, isocyanates, isothiocyanates and heavy metal ions such as Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Pb+2, Ru+2 and Zn2+. Si-Trisamine has a number of uses, it is a very powerful scavenger of transition metals and can also be used as a work-up tool to remove electrophiles or acids in either batch or flow-mode (cartridge) following traditional reflux heated or microwave synthesized reactions.

Metal Scavenging

Heavy metals such as palladium, copper and tin are widely used in diverse transformations and their removal following organic synthesis has become a vital part of the API scale-up process. Si-Trisamine was applied successfully in the scavenging of palladium acetate, copper sulfate and nickel acetate from aqueous and organic solutions.
