An embodiment of the present invention is a method for isolating conducting polymer precursors by contacting a non-basic heterocyclic nitrogen containing hydrocarbon stream having a boiling point of from 232 ~C (450 ~F) to 566 ~C (1050 ~F) with an effective amount of a treating agent selected from monohydroxyl alcohols having a density at 25 ~C of less than 0.90 g/cm3 and mixtures thereof, at conditions effective to maintain the reactants in a liquid phase to produce a first stream enriched in non-basic heterocyclic nitrogen containing hydrocarbon compounds and a second treated stream having a decreased non-basic heterocyclic nitrogen content. Optionally, an effective amount of mineral acid may be added to the hydrocarbon stream to enhance the process.

La présente invention porte sur un procédé d'isolation de précurseurs polymères conducteurs qui consiste à mettre en contact un flux d'hydrocarbure contenant un azote hétérocyclique non basique dont le point d'ébullition est compris entre 232 ·C (450 ·F) et 566 ·C (1050 ·F) avec une quantité efficace d'un agent de traitement sélectionné parmi des alcools monohydroxyle ayant une densité à 25 ·C inférieure à 0,90 g/cm?3¿ et des mélanges de ceux-ci, dans des conditions efficaces pour maintenir les réactifs en phase liquide afin de produire un premier flux enrichi dans des composés d'hydrocarbure contenant un azote hétérocyclique non basique et un second flux à teneur réduite en azote hétérocyclique non basique. Une quantité efficace d'acide minéral peut être éventuellement ajoutée au flux d'hydrocarbure pour améliorer le procédé.
