    Photo-oxidation of Alkylbenzenes Initiated by 1-Naphthol
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (07), 1974) Klein, Allan E.; Pilpel, Neiton
    The addition of 1-naphthol accelerates the photo-oxidation of alkylbenzcncs when their alkyl group contains a reactive hydrogen atom. From the effects of u.v. light on dilute solutions of 1-naphthol in cumene, s-butylbcnzcnc and t-butylbcnzene, which have been floated as layers on water, it is possible to propose a mechanism by which the alkylbenzcncs arc oxidised under the influence of u.v. light.

    Photo-oxidation of Floating Hydrocarbon Oils in the Presence of some Naphthalene Derivatives
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (1), 1978) Sanniez, William H. K.; Pilpel, Neiton
    Samples of pure isopropylbenzene and methylbenzene and of a commercial mineral oil, Dobane, containing various concentrations of 1-hydroxynaphthalene, naphthalene-a-aldehyde and 1-nitro- naphthalenc were floated on water as layers 0.6 cm thick, and irradiated with ultraviolet light over periods of 240 min. By combining measurements of the changes occurring in interfacial tension with chemical and physical analysis of the oil and water phases, it has been possible to identify some of the products of photo-oxidation and to propose mechanisms for the reactions.
