The ozonolysis of primary aliphatic amines in fine particles

The ozonolysis of primary aliphatic amines in fine particles

The oxidative processing by ozone of the particulate amines octadecylamine (ODA) and hexadecylamine (HDA) is reported. Ozonolysis of these amines resulted in strong NO−2 and NO − 3 ion signals that increased with ozone exposure as monitored by photoelectron resonance capture ionization aerosol mass spectrometry. These products suggest a mechanism of progressive oxidation of the particulate amin...

Aliphatic amines in Chesapeake Bay sediments

Aliphatic amines were determined in sediments and sediment pore waters from several contrasting sites in Chesapeake Bay. The aliphatic amines diethylamine, set-butylamine, n-propylamine, and i-propylamine were detected in a limited number of pore-water samples at concentrations generally less than 0.6 /IM. The occurrence of these amines showed no obvious correlation to other sediment geochemica...

Application of Polypyrrole Coated Stainless-Steel Wire to the Headspace Solid-Phase Microextraction of Aliphatic Amines

The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...
