a Johnson Matthey Company, is introducing a new line of anhydrous solvents featuring
the new Active Dry™ alkali metal silica gel system (Na-SG-I), an efficient
drying agent and impurity remover for solvents and anionic polymerization processes.
Commonly used drying agents require distillation to remove traces of the agent.
Standard drying procedures are also a tedious limiting factor in both at laboratory
and industrial production scale reactions.
Active Dry™ provides drying performance on par with other recognized
methods with the added benefit of not requiring a post-drying and post-purifying
workup. Each Active Dry™ solvent includes an Active Dry™ pouch immersed
in the solvent to ensure dryness, and is sealed using Alfa Aesar’s exclusive
ChemSeal™ septum caps. The initial line of solvents includes benzene,
heptane, hexane, pentane, tetrahydrofuran and toluene.
