| p-Chlorphenols werden mit 600 ccm zehnfach normaler Kalilauge I2 Stunden bei I95 bei Gegenwart von metallischem Kupferim Druckgefab geschuttelt. Nach dem Ansauern mit etwa 450 ccm konzentrierter Salzsaure wird zur Entfernungdes unveranderten p-Chlorphenols Dampf durchgeblasen und beide Flussigkeiten extrahiert. Die Ausbeute an Hydrochinon betragt 74 Prozent der Theorie. |
