Quaternaries as intermediates in the thermal and oxidative degradation of alkanolamines / Stephen A. Bedell in Industrial & engineering chemistry research, Vol. 49 N° 16 (Août 2010)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 16 (Août 2010) . - pp. 7147–7151 Titre : Quaternaries as intermediates in the thermal and oxidative degradation of alkanolamines Type de document : texte imprimé Auteurs : Stephen A. Bedell, Auteur ; Clare M. Worley, Auteur ; Rida Sadek Al-Horr, Auteur Année de publication : 2010 Article en page(s) : pp. 7147–7151 Note générale : Indusrtrial chemistry Langues : Anglais (eng) Mots-clés : Thermal Oxidative Degradation Résumé : Mass spectral evidence is presented for the formation of quaternaries in the high temperature (140 °C) autoxidation of MDEA. Additionally it is demonstrated that the quaternary reacts with neutral amines in a manner consistent with an SN2 mechanism. Rate studies are presented which could be extended to include a systematic variation of nucleophiles, quaternaries, temperature, and solvent composition and allow precise modeling of thermal degradation.
