Zusammenfassung:	A method for the purification of impurities from tall oil feed, and a corresponding liquid product obtained by the method, is provided comprising mixing the tall oil feed with an added solvent, removing impurities that precipitate when the solvent is added, and then recovering a liquid product as a tall oil feed with a reduced impurity content. Menetelmä epäpuhtauksien puhdistamiseksi mäntyöljysyötteestä ja menetelmällä saatu vastaava nestetuote saadaan, kun sekoitetaan mäntyöljysyötettä lisätyn liuottimen kanssa, poistetaan epäpuhtaudet, jotka saostuvat liuotinta lisättäessä, ja sitten otetaan talteen nestemäinen tuote vähemmän epäpuhtauksia sisältävänä mäntyöljysyötteenä.
