WebDiphenylamine is an organic compound with the formula (C 6 H 5) 2 NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. Diphenylamine dissolves well in many common organic solvents, and is moderately … WebCentrifugation allowed for the isolation of pure phenylsodium which appears as a yellowish-white amorphous powder which readily bursts into flames. Like phenyllithium, adducts of the compound with PMDTA have been crystallized. While phenyllithium forms a monomeric adduct with PMDTA, phenylsodium exists as a dimer, reflecting the larger radium ...
