Abstract

Partially degraded, aqueous methyl diethanolamine solutions were analyzed by a gas chromatograph equipped with a Tenax column and flame ionization detector; nitrogen was used as the carrier gas. To aid in product identification, the gas chromatograph was coupled to a mass spectrometer operating either in electron impact or chemical ionization mode. The most important degradation products were found to be: methanol, ethylene oxide, trimethylamine, ethylene glycol, 2-(dimethylamino)ethanol, 1,4-dimethylpiperazine, N-(hydroxyethyl)methylpiperazine, triethanolamine; and N,N-bis(hydroxyethyl)piperazine.
