    Solvents like acetonitrile, dimethylsulfoxide (DMSO) and acetone can be dried with CaH 2 and then distilled under inert gas. Acetonitrile and acetone can be dried over P 4 O 10 to remove trace amounts of water. In the presence of larger amounts of water, these compounds form condensation products and have to be pre-dried with Calcium hydride.
