Abstract
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/cm 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.
