Quand le naphthalène en solution dans des mélanges d'alcanes ou d'alcools est irradié à des longueurs d'onde ≤ 315 nm, il est détruit par une série de réactions qui sont fortement accélérées à haute pression. Les analyses GC-MS des photoproduits recouvrés après montée à très haute pression (> 5GPa) montrent que plusieurs réactions sont impliquées : 1) la photolyse sensibilisée des molécules de solvant en radicaux alkyles et alkoxyles ; 2) la réduction du naphthalène en tétrahydronaphthalène et radicaux hydronaphthyles ; 3) la polymérisation des radicaux hydronaphthyles et alkyles en dimères, trimères et polymères ; 4) la photoaddition des radicaux du solvant sur le naphthalène ; et 5) l'échange H-D entre le naphthalène et les molécules de s...
