Abstract

Protic asphaltene ionic liquids comprising chemically modified asphaltenes are provided. The asphaltenes are modified via carboxylation and formation of alkyl and/or aryl imidazole derivatives. Chemical modification of the asphaltenes results in their stabilization e.g. in heavy petroleum crude, and prevents their aggregation and precipitation.
