17. Use Of SiliaBond® DMT
SiliaBond® DMT (Si-DMT) is the silica bound equivalent of 2,4,6-trimercaptotriazine (trithiocyanuric acid). It is a versatile metal scavenger for a variety of metals including Cd, Co, Ni, Pd, Pt, Rh, and Ru under a wide range of conditions and the preferred metal scavenger for ruthenium catalysts.
TMT has been reported to efficiently remove palladium and heavy metals by precipitation. Unfortunately, its solubility in organic solvents causes problem. SiliaBond DMT solves this issue and almost all solvents can now be used.
SiliaPrep Metal Scavengers will lower the residual metal concentration of various metal complexes to single digit ppm.
