Abstract:
A method for isolating conducting polymer precursors consisting essentially of: contacting a non-basic heterocyclic nitrogen containing hydrocarbon stream having a boiling point of from 232Â° C. (450Â° F.) to 566Â° C.) 1050Â° F.) with an effective amount of from 10-200 vol % a treating agent selected from monohydroxyl alcohols having a density at 25Â° 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 hydrocarbon stream enriched in non-basic heterocyclic nitrogen containing hydrocarbons and a second treated hydrocarbon stream having a decreased non-basic heterocyclic nitrogen content.
