Molten naphthalene provides an excellent solubilizing medium for poorly soluble aromatic compounds. Zobacz więcej Naphthalene is an organic compound with formula C 10H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 Zobacz więcej In the early 1820s, two separate reports described a white solid with a pungent odor derived from the distillation of coal tar. In 1821, Zobacz więcej Reactions with electrophiles In electrophilic aromatic substitution reactions, naphthalene reacts more readily than benzene. For example, chlorination and bromination of naphthalene proceeds without a catalyst to give In terms of Zobacz więcej Naphthalene is used mainly as a precursor to derivative chemicals. The single largest use of naphthalene is the industrial production of Zobacz więcej A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). The eight … Zobacz więcej Most naphthalene is derived from coal tar.
