Siloxene is fluorescent and red chemiluminescence results from oxidation with ceric sulfate, chromic acid, potassium permanganate, nitric acid, and several other strong oxidants. The chemiluminescence spectmm peaks at 600 nm and has been reported (199) to give a maximum brightness of 3.43 cd/m (1 footlambert). 

The methyl group of -nitrotoluene is activated by the para nitro group. -Nitrotoluene is oxidized to -nitrobenzoic acid [62-23-7] by potassium hexacyanoferrate(III) in alkaline solution, potassium permanganate, or potassium dichromate. -Nitrotoluene is converted to -nitrobenzaldehyde... 

The common treatment methods are acidification, neutralization, and incineration. When oxahc acid is heated slightly in sulfuric acid, it is converted to carbon monoxide, carbon dioxide, and water. Reaction with acid potassium permanganate converts it to carbon dioxide. Neutralization with alkahes, such as caustic soda, yields soluble oxalates. Neutralization with lime gives practically insoluble calcium oxalate, which can be safely disposed of, for instance, by incineration. 

Alkanolamines can be oxidized with various oxidiziag agents. With acidic potassium permanganate or excess potassium hydroxide, the potassium salts of the corresponding amino acid are obtained... 

Separated polyols are detected by a variety of reagents, including ammoniacal silver nitrate (175), concentrated sulfuric acid, potassium permanganate (163), lead tetraacetate, and potassium teUuratocuprate (176). A mixture of sodium metaperiodate and potassium permanganate can be used to detect as htde as 5—8 ).tg of mannitol or erythritol (177). 

Chlorate Analysis. Chlorate ion concentration is determined by reaction with a reducing agent. Ferrous sulfate is preferred for quaHty control (111), but other reagents, such as arsenious acid, stannous chloride, and potassium iodide, have also been used (112). When ferrous sulfate is used, a measured excess of the reagent is added to a strong hydrochloric acid solution of the chlorate for reduction, after which the excess ferrous sulfate is titrated with an oxidant, usually potassium permanganate or potassium dichromate. 

Pyridazinethiones are readily oxidized to the corresponding disulfides with iodine, aqueous iron(III) chloride, hydrogen peroxide in acetic acid, potassium permanganate in acetic acid, and upon long exposure to air. 

Oxidation (Section 11.13) Oxidation of alkylbenzenes occurs at the benzylic position of the alkyl group and gives a benzoic acid derivative. Oxidizing agents include sodium or potassium dichromate in aqueous sulfuric acid. Potassium permanganate (KMn04) is also an effective oxidant. 

In an attempt to protect thiophenols during electrophilic substitution reactions on the aromatic ring, the three substituted thioethers were prepared. After acetylation of the aromatic ring (with moderate yields), the protective group was converted to the disulfide in moderate yields, 50-60%, by oxidation with hydrogen peroxide/boiling mineral acid, nitric acid, or acidic potassium permanganate. ... 

It yields on reduction dihydrocopaene, a compound boiling at 118° to 121° at 12 mm. By oxidation hy ozone or hy permanganate of potassium it yields a ketonic acid of the formula CijH Oj, which forms a semicarbazone melting at 221°. These derivatives characterise copaene AS a new sesquiterpene. Its characters, however, have only heen very slightly investigated at present. 

On oxidation with permanganate of potassium it yields sabinol-glycerine, CjoH,5(011)3, melting at 152° to 153°, and by further oxidation, tanacetogene-dicarboxylic acid, CpHj Og, melting at 140°. On reduction with sodium and amyl alcohol, sabinol yields thujyl alcohol, CjoHj OH.

On oxidation with permanganate of potassium, this phenol ether yields tetramethoxy benzoic acid, C H(OCH3)4COOH, melting at 87°. 

Use Appendix 2B to determine whether an acidic-potassium permanganate solution can oxidize (a) chloride ions to chlorine and (b) mercury metal to mercurv(I) ions under standard conditions. 

When it is mixed with small quantities of sulphuric acid and in the presence of water traces, it is thought to form permanganic acid, HMn04, which is very unstable and a violent oxidant. Thus, this system incandesces in the presence of ammonia. Mixtures of potassium permanganate /peroxomonosulphuric acid have also been used to measure sulphur in the presence of carbon. However, this is not recommended since it is highly likely to detonate.
