The formation of N,N-dimethylcarbamoyl chloride (DMCC) in Vilsmeier reactions (VRs) and the hydrolysis of DMCC during aqueous workup were investigated. The amount of DMCC formed was dependent on the chlorination reagent. The activity order was found

The complementary use of gas chromatography-mass spectrometry (GC-MS), gas chromatography-atomic emission detection (GC-AED) and nuclear magnetic resonance (NMR) spectroscopy is demonstrated by the identification of four major by-products in a sample

It has been shown that some of the fluorinated ethane derivatives being introduced as CFC-replacements can be transformed to TFA (trifluoroacetate) in the atmosphere. Moreover, TFA is extremely stable in the environment, and this has raised questions

The presence of organically bound halogens in precipitation was studied by first adsorbing organics on activated carbon and then analysing the chloride, bromide and iodide formed during combustion of the carbon. A standard instrument for the group pa

A study was undertaken to investigate whether pyrolysis–gas chromatography (Py–GC) can be used to analyse organic compounds, in particular chloroorganic compounds, present in precipitation. Samples of rain and organic extracts of such samples wer

Information about the occurrence and chemical character of adsorbable organic halogens (AOX) in surface water and precipitation is reviewed and updated with results from on‐going studies. There is now very strong evidence that the widespread occurr

Organic matter in samples of rain and snow from Sweden, Poland, Germany and the Republic of Ireland was fractionated by employing a series of filtration, purging, evaporation and extraction steps. Determinations of the group parameter AOX (adsorbable

The average concentration of AOX (adsorbable organic halogens) in precipitation was found to vary from 2 – 3 µg Cl/L at remote sites in northern Sweden and Finland to approximately 10 µg Cl/L further to the south in the Baltic Sea region. By usin
