CONTACTThe organic synthesis methods using transition metal catalysts have been utilized in many applications these days such as “Suzuki-Miyaura” reaction. The removal of used metals from the reaction system was a major issue, and removing the residual heavy metals is just as important as developing the catalyst reaction process.
One of the removal methods is introducing a functional group that specifically binds metal to the solid surface and using it as a scavenger. We manufacture SCAVENGER SILICA with various functional groups on silica gel with large surface area, porous material.
It has high strength and solvent resistance. It can be widely used from research to plant level.
FEATURES
Selectivity of Functional Groups
Several metals like palladium are used as catalysts for organic synthesis. We can offer four grades with high adsorption properties for selective removal of each metal residue.
Easy Handling
SCAVENGER SILICA series is spherical type and particle with 100 μm. It is easy to pack in columns and has high filtration properties. It can be used from laboratory to industrial-scale processing.
