Phosphorus penloxide

Preparation. Collins and Hess have published a detailed procedure for preparation of the reagent from chromium(Vl) oxide (dried over phosphorus penloxide) and pyridine (reagent grade). Caution The reaction is extremely exothermic. The chromium(Vl) oxide should be added to pyridine at such a rate that the temperature docs not exceed 20° and in such a way that the oxide mixes rapidly with pyridine. As the...
