Introducing Active Dry™ Anhydrous Solvents from Alfa Aesar

Alfa Aesar, 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 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.

A full listing of products included in the addendum can be accessed at www.alfa.com/en/product/active dry.
