450 grams of 3 times freezed safrole with sg of 1.096 was put in 3 necked rb flask,attached termometer and heated to 150C.Safrole immediatly turned brown and then almost black.Left to stir at same temp with overhead stirring.Came back 16 hours and tried to distill at atmospheric,most of it came over between 235-240 degrees C.KOH flakes were completely decomposed to small particles.Distillate smells wierd,not like safrole nor isosafrole.Was put in freezer 10 minutes ago to see if it froze.Will post results soon.Raf thinks water might have been problem.He has followed many of these "easy-iso" procedure without success,only CaO/KOH has worked without much problems.Maybe vacuum isomerization will work,not sure,will try someday.
