Abstract

Oppfinnelsen vedrører en fremgangsmåte for å fremstille høyrent hydrokinon uten forurensninger resulterende fra dets fremstillingsprosess. Fremgangsmåten ifølge oppfinnelsen er kjennetegnet ved at den omfatter i det minste de etterfølgende trinn: a) rå-hydrokinonet i en flytende form og omfattende i det minste resorcin og pyrogallol som en forurensning, underkastes en kontrollert avkjøling som sikrer krystallisering av det rene hydrokinonet, b) de rene hydrokinonkrystallene separeres fra modervæskene, c) oppvarming og delvis smelting gjennomføres, d) det rensede hydrokinonet smeltes fullstendig, og e) det rensede hydrokinonet utvinnes.
