Zusammenfassung:	Acidic and basic ion‑exchange resins were prepared by chemical modification of petroleum asphaltenes. The resulting products were characterized by IR spectroscopy and MALDI mass spectrometry. Feasibility was demonstrated for carrying out catalytic acylation of salicylic acid in the presence of acidic and basic catalysts derived from petroleum asphaltenes to give acetylsalicylic acid. Asphaltene‑derived ion‑exchange resins containing either sulfonic acid (SA) or amino groups (AA) were used as catalysts. These catalyzed reactions gave acetylsalicylic acid in 78% and 73% yield, respectively.
