Usage

General Description

Methylene chloride (13C) is a stable and non-reactive isotope of methylene chloride, a colorless, volatile liquid commonly used as a solvent and paint stripper. As an isotope, it is a carbon-based compound with a unique carbon-13 atom, which is often used in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry for research and analytical purposes. The presence of the stable carbon-13 isotope allows for more precise and accurate analysis of the molecular structure and behavior of methylene chloride, making it an important tool for chemical research and analysis. Additionally, carbon-13 labeling can provide valuable information on metabolic processes and the fate of organic compounds in the environment.

Selective monooxidation of light alkanes using chloride and iodate

We describe an efficient system for the direct partial oxidation of methane, ethane, and propane using iodate salts with catalytic amounts of chloride in protic solvents. In HTFA (TFA = trifluoroacetate), >20% methane conversion with >85% selectivity for MeTFA have been achieved. The addition of substoichiometric amounts of chloride is essential, and for methane the conversion increases from 20%. The reaction also proceeds in aqueous HTFA as well as acetic acid to afford methyl acetate. 13C labeling experiments showed that less than 2% of methane is overoxidized to 13CO2 at 15% conversion of 13CH4. The system is selective for higher alkanes: 30% ethane conversion with 98% selectivity for EtTFA and 19% propane conversion that is selective for mixtures of the mono- and difunctionalized TFA esters. Studies of methane conversion using a series of iodine-based reagents [I2, ICl, ICl3, I(TFA)3, I2O4, I 2O5, (IO2)2S2O 7, (IO)2SO4] indicated that the chloride enhancement is not limited to iodate.
