Abstract

Det er beskrevet en fremgangsmåte for å oppnå fettsyrealkylestere, kolofoniumsyrer og steroler fra råtallolje (CTO), som er kjennetegnet ved følgende trinn: (b) omsetning av den fiie fettsyren til stede i CTO med lavere alkoholer; (c) separering av fettsyrelaverealkylesteme som derved oppnås fra gjenværende CTO for å fremstille en første sttøm av fettsyreestere; (d) forestring av sterolene i det gjenværende CTO med borsyre; (e) separering av de gjenværende kolofoniumsyrene fra sterolboratene på forhånd oppnådd for å fremstille en andre sttøm av kolofoniumsyrer; og (f) omdanning av nevnte sterolborater til de frie sterolene for å fremstille en ttedje sttøm av fiie steroler.
