Wet oxidation tests were performed on two pure compound streams: acetic acid and ammonia; and on two wastewater streams: acrylic acid wastewater and sulphide laden spent caustic. Test results showed that Mn/Ce and Pt/TiO2 were effective catalysts that greatly enhanced acetic acid, ammonia and acrylic acid wastewater destruction. However, the Mn/Ce catalyst performance appears to be inhibited by concentrated salts dissolved in solution. This could limit the applicability of this catalyst for the treatment of brackish wastewaters. Zr, Ce and Ce nanoparticles were also shown to exhibit some catalytic activity, however not to the extent of the Mn/Ce and the Pt/TiO2.

4-Benzoyl-5-phenyl-2,3-dihydrofuran-2,3-dione (1) reacts with aldehydes or ketones via the acylketene-intermediate (2) yielding the 1,3-dioxin-4-ones (3). The aldehyde derivatives (3 a-e) can be converted into the anilino-chalcone (5) or the anilino acrylic acid (6) by treating with aniline at 20 °C. 6 and diazomethane combine to the acrylic acid methyl ester (7), which by heating (200 °C) is cyclisized to the quinolin-4-ole (8). On the other hand, the keto derivatives 3f-h and aniline give the dibenzoyl acetic acid anilide (9).
