1. Förfarande för ätervinning av antracen son fällning frän kreosotdestillationsfraktion av stenkolstjära, vilken fraktion innehäller antracen och antingen fenantren, karbazol eller bäda, varvid ätervinning utförs genom avkylning av en flytande kreosotdestillationsfraktion frän en första temperatur, vid vilken antracen är i form av vätskefas, tili en andra temperatur, vid vilken antracen utfälls, känneteck-n a t därav, att en keton med 3-6 kolatomer inblandas i den flytande kreosotdestillationsfraktionen före utfällning av antracen, varvid mängden keton är tillräcklig för att bibehälla fenantren och/eller karbazol i form av vätskefas vid den andra temperaturen för bildning av en sadan fällning, som innehäller ätminstone 75 vikt-% antracen.
2. Förfarande enligt patentkrav 1, kännetecknat därav, att ketonen är aceton.
3. Förfarande enligt patentkrav 1 eller 2, kännetecknat därav, att ätminstone ca 90 viktprocent av fällningen är antracen.
4. Förfarande enligt patentkrav 1 eller 2, kännetecknat därav, att den andra temperaturen ligger mellan ca -10°C och ca 15°C. Il
