Drying of Organic Solvents THF, Toluene, MDC (DCM), Acetonitrile, Ether

A recent paper that describes an easier way of drying the common organic solvents than the hazardous, distillation stills.

Reported Procedure :

Analytical reagent- or HPLC-grade solvents were obtained  from commercial sources and used as is or were dried using the  various methods described herein. Desiccants (3 A ° molecular sieves, various silicas, neutral alumina) were obtained from commercial suppliers and were predried at 300 C for 24 h immediately before use. Solvents were dried either by allowing them to stand over the desiccant under nitrogen or by passing the solvent over a column of the desiccant as specified, inside the glove box..
