Submicrodetermination of oxygen in organic compounds

Microchemical Journal, 1965
Summary A method for the submicrodetermination of oxygen in organic compounds is described. The sample is heated with mercuric chloride in an evacuated sealed tube in order to convert all of the oxygen in the sample to carbon monoxide or carbon dioxide, or both.

Structure of Organic Oxygen Compounds of Sulphur

Russian Chemical Reviews, 1968
The nature of the sulphur–oxygen bond, the geometry of molecules of the types XYSO, XYSO2, XSOOH, and XSO2OH, and the character of the intramolecular interactions in these compounds are discussed. Apart from the σ-bond between sulphur and oxygen, interaction obviously occurs by means of the 3d-orbital of sulphur and the 2p-orbital of oxygen (2p–3d ...

The oxidation of organic compounds by “singlet” oxygen

J. Chem. Soc. B, 1966
The normal or “triplet” ground state (3Σg–) of molecular oxygen is that of a biradical, ·O–O·, but “singlet” oxygen (1Δg) OO, which is structurally similar to ethylene, is the initial product of heterolytic decompositions of hydrogen peroxide or of per-acids.

Coulometric microdetermination of oxygen in organic compounds

Microchemical Journal, 1970
Summary Application of coulometry to the microdetermination of oxygen in organic substances using a newly designed Pt P 2 O 5 electrolytic cell has been investigated. A sample is pyrolyzed in a nitrogen stream, the gaseous products are passed over carbon, platinized carbon, and reduced copper.
