A new method for the determination of oxygen in organic compounds

Analytica Chimica Acta, 1955
Abstract Oxygen in compounds of carbon, hydrogen, and oxygen can be determined by heating the sample with an excess of strontium oxide and graphite in. a nickel bomb or sealed Vycor glass tube. During the heating period, three hours at 650° C, the oxygen of the sample is converted to carbonate. The carbonate is then determined volumetrically.

Controlled oxidation of organic compounds in oxygen plasma

Vacuum, 2003
Abstract The etching of different polymers versus the dose of neutral oxygen atoms was measured in an oxygen plasma post-glow reactor. The source of neutral oxygen atoms was an inductively coupled RF oxygen plasma with an electron temperature of 5 eV and a density of about 10 16  m −3 .

Micro and trace determination of oxygen in organic compounds

Analytica Chimica Acta, 1978
Abstract Samples are pyrolyzed over carbon in helium doped with chloropentane, which enhances the liberation of the oxygen. The carbon monoxide formed is determined by gas chromatography. A modification of a Carlo Erba CHN+O Elemental Analyzer is described, and results of micro and trace determinations in organic and inorganic compounds are reported.

Oxygen Isotope Exchange Reactions of Organic Compounds

1965
Publisher Summary Isotope exchange reactions are reversible chemical processes in which two isotopes C and C* of the same element exchange places. No net chemical change takes place in these reactions, but only interchange of the isotopic label occurs.
