Assuming no prior knowledge, the book discusses everything from the simplest mixed acid nitration of toluene, to the complex synthesis of highly energetic caged nitro compounds. Then, a lone pair of nitrogen will form a triple bond and expel a leaving group. Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis: P 4 O 10 (am) + 6H 2 O (lq) → 4H 3 PO 4 (c) (-177 kJ ) However, its utility for drying is limited somewhat by its tendency to form a protective viscous coating that inhibits further dehydration by unspent material. P2O5 (or P4O10) can be prepared by burning elemental P4 (tetra-phosphorus) in an environment containing a sufficient amount of oxygen. Besides it is used in the oxidation of ethanol to ethanale and in the production of phthalic anydride, polyamide, oxalic acid and further products. February 2020.
