In Addition to Rhodium's reply on standard practice, I'd like to add a word of caution to guard against a false sense of security, concerning gaaks.
This word of caution in no way, shape, or form negates the need to do that solvent wash as Rhodium suggests! It's still a standard practice and should be followed.
If the gaak made it that far into the rxn, it's HIGHly unlikely that a solvent wash will remove it from the end product.
SWIKC made a statement concerning an important discovery about amine solubility and acetone.
Really not sure if the rxn itself has rearranged the amine structure in the presence of certain gaaks or whether these gaaks are included to work that way right off the bat.
But it's been noticed that when Eudragit makes it through rxn, meth will be more readily dissolved in acetone at a greater rate than has been observed in the past.
There may be a solvent activation needed to affect this change since it's not believed to have been pH activated as what was previously thought by Ibee.
I will say this about that!
Some more confirming evidence has been personally established by Ibee HIGH and StaffMember
that warrants a health related warning regarding gaak infected meth.
If you know it's gaaked...don't do it!
It will make you sick and it has made Ibee sick on two occassions now.
Embarrassing but true that Ibee recreated a scenario he swore to never repeat.
This gaak was not detected anywhere in the process through to the final work-up and consumption.
The next day a layer of CRYSTAL CLEAR gel, half an inch thick was discovered floating atop the post-rxn distillation flask!
The consumed product could not have been relieved of that Gel as it was titrated and not steamdistilled.
The spent basified solution from the titrated first pulls did not contain the Gel.
Just the last parts that were distilled.
HIGHly pissed at the discovery...Ibee trashed yet another batch remnant instead of blasting away!
In the clean of that pfed...Ibee did not adhere to protocol because he lacked one chem used in the extraction process and had no way to aquire any being "UnderTheWeather".
The extraction method to use must contain components geared toward the removal of Eudragit.
Look it up and follow the latest extraction methods if you want to bee spared.
The way eudragit works and what makes it effective is it's modified release capability to bypass the normal digestive routes. It's a tricky Gaak to detect but you'll know it after it smacks ya around a bit!
Nastynasty Gakk!
The word of caution here is:
Make sure positively that these specialty gaaks are removed pre-rxn!
That's all I can say!
