Hello again;
SWIS just popped in to tell me that, after I gave him the info yesterday regarding his long reflux questions, that he started a 6gm Pseudo (HCl), 10 gm I, 3.5gm RP reflux in a round bottom boiling flask set in an oil bath, and hooked up to his handy-dandy home-made Ghetto Blaster condenser, which consists of a piece of aquarium tubing stuck in one-hole stopper, wound around a peice of 1" plastic PVC pipe about 20 times, and then draped over a hook in the cieling and capped off with a party balloon. After about 18 hours of reflux at ~ 220 degrees(F), he noticed that the bottom portion and first two wraps of the tubing were a reddish purple color, and the rest of the tubing all the way up to the top of the PVC pipe was a yellowish color, starting from the top of the reddish purple color, where it was a dark golden brown, up to the top of the PVC, where is was a thin, yellowish color. Now SWIS knows that honey is that very same color, and was afraid that perhaps the tubing was absorbing some of his honey that was coming up in the reflux. Could this be the case? I will pass on whatever info you bees might have about this phenomenon.
Thanks,
Silmarillion
