H2SO4 + 55 cm3 H2O, and/or with 10 wt% Na2SO3 aq. ― approx. 1 vol% washing solution : ether, repeatedly. That should be followed by washing with distilled water, drying with anhydrous CaCl2 (1 day), and filtering. Alternatively, it can be dried with activated anhydrous alumina or with 4Å molecular sieves. Further purification (if required) can be achieved by distillation, possibly over sodium wire or P2O5.
