Descrizione

Descrizione generale

p-Benzoquinone (PBQ) is a cyclic conjugated diketone. Its high-resolution photoelectron spectrum has been reported. The visible and near ultraviolet spectra of PBQ have been recorded and analyzed. Its addition as coagent has been reported to enhance the crosslinking rate of polypropylene initiated by the pyrolysis of peroxides. Its impact on hemoglobin (Hb) has been investigated based on immunoblots and mass spectral analysis of a smoker′s blood.
