Saying that Platcat suffered an incomplete reaction begs the question. The question we want to answer is
why was the reaction incomplete?
It could have been inadequate red, dirty red, or red that coated during the reaction by a contaminant. We have to trust to Platcat's opinion of how good his red was to start with, and he's not new at this. His symptoms could be explained by povidone, as heavy povidone contamination can coat the red and impair the recycling of I2 to HI causing the reaction to only partially complete. The bright yellow? Can't say its all iodine, as incomplete reactions will have yellow honey, but not necessarily bright piss-yellow honey. I've seen that color many times, but haven't seen it since Placebo told us about the turps cure. The Straight to E does not necessarily address povidone...and I think that is a logical culprit in Platcat's situation. Platcat may have extracted from some pills with povidone as a foilant rather than as a binder or glue, and his assessment of povidone as a possible source of his incomplete reaction is a good one.
Or his red might be dirtier or more used up than he thought, since he was reacting mbrp-- which will vary in quality.
I am looking forward to Scottydog's results with the stuff he reacted. I think Wareami's observation about a tetra wash is an excellent one. With the variety of foilants in the mix, its really hard to expect to be able to beat evry formulation with a single process. Knowing which ingredients dictate which approach will probably continue to be a vital tool in the extractomaniac's bag of tricks.
I look forward to more yield and purity reports...surely more of you have some results to share with us by now. I guess I'll go hunt down that damn phos fairy and unlock the lab again and find out for myself....I've already concluded the being clean and sober stuff
isn't what its cracked up to be...
