TL;DR: In this paper, the reaction between naphthalene and oxygen in supercritical water (SCW; 374°C, 22.1 MPa) has been studied in a batch reactor of 6-ml volume placed in a fluidized bath.
Abstract: The reaction between naphthalene and oxygen in supercritical water (SCW; 374°C, 22.1 MPa) has been studied in a batch reactor of 6-ml volume placed in a fluidized bath. Reaction temperature varied from 300°C to 420°C, while pressure varied from 18 to 29.3 MPa. These conditions corresponded to both subcritical and supercritical water. Conversion of naphthalene in supercritical water reached about 99%; more than 80% of carbon appeared as CO 2 within 300 s reaction time. The effect of time and O 2 concentration on CO 2 yield was determined. Intermediate species formed during naphthalene oxidation in SCW were identified and quantified for the first time. They included acetic acid, ketone, and carboxyl compounds. Two main products observed in the aqueous phase were acetic acid and formic acid. Naphthoquinone, salicylaldehyde, 2′-hydroxyacetophenone, salicylic acid, phthalic anhydride, phthalide, chromone, 1,4-naphthoquinone, 1-naphthol, dibenzofuran, and fluorenone were identified during the SCW oxidation of n...

TL;DR: In this article, the electrochemical reductions of fluorenone hydrazone (Fl=NNH2) and benzophenone analogs were studied at platinum cathodes in DMF−0.1 M(n-Bu)4NClO4 in the absence and presence of an added proton donor.
