AFOAF Help with E/P/I method
Good evening,
AFOAF has been researching/ considering the RP/I/E method for a while now. And would like clarification before such materials could be wasted.
Say 100g's of Eph tablets are crushed and put into a jar. With double the volume of methanol (Swim is assuming meth spirits is the substance of choice) And shaken for around 20 minutes then left to settle before the top layer is taken off (Meth) This process will be repeated 3 times, and reduced on a electric hotplate. Then acetone is added twice the amount he believes, then allows the remaining liquid to be evaporated.
Reports suggest he will be left with 'dirty ephedrine'. AFOAF will add this to a suitable glass and add a safe amount of toluene and allow to boil whilst stirring. He will allow it settle for a few minutes then filter the solution through filters and in the paper should be left with pure EPH. This process will happen until no contaminants are found in the toluene solution. So with the clean EPH he will add distilled water and acetone and apply to the boil lightly. Then filter off the acetone (in a coffee filter) then he believes he is ready for the reaction.
He understands the 1/1/0.33 ratio (E/I/RP) and has a ice bucket prepared for the reaction flask.
He will add the respective ratio weights into the flask and place the condensor on the flask and allow distilled water to pass through to the mixture. Removing and re-adding the flask to and from the icebath for a controlled reaction! Then when the mix has slowed or even stopped he will apply to some heat to continue reaction for a hour or so...then after remove the condensor and add ice water then add the Lye (NaOH) bringing the reaction to 14pH / alkaline substance.
Now distillation can take place... With condenser and tube attached from the reaction flask to a separate vessel and heat the cooker and the reaction flask and should receive the distilled product with water on the bottom (top layer being freebase?!?)
Then to crystallize the freebase he should just throw a little toluene into jar, and then separate! Now your absolutely pure meth freebase is in the toluene.
How would he go about removing the freebase from the toluene? And are all the above procedures correct before AFOAF tries such a activity?
Thank you kindly in advance
