Little bit off topic, but still about methylphenidate extraction.. I'm not really looking to make Ritalin Crack (don't let the media catch on to this one), because I honestly don't know anyone that would dare to smoke something even resembling crack.
I had some leftover methylphenidate XR tablets which I dissolved in 2-propanol 99.9% (= IPA)... Of course I was stupid enough not to check out the ingredient Ethyl Cellulose, a Polymer that is soluble in IPA.
Ingriedients are:
Methylphenidate HCl
Ethyl Cellulose
Talc
Magnesium Stearate
Seems to me that with these ingredients a water extraction would have been the best option. None of the inactive components are soluble in water.
Anyway.. The solution is slowly dripping through a coffee filter as we speak.. It has been for almost two days now and about 2/3 of the solution has passed through. I was wondering what should be done next.
I'm considering putting in a new filter because this one might not work so well anymore.. I'm willing to give it another two days though.
When all is filtered, I should have a solution of IPA, Ethyl Cellulose and Methylphenidate right?
I was thinking about adding a small amount of water to the solution (100 ml's) and heat the solution until the IPA has evaporated.. The Ethyl Cellulose should become solid and I'll filter again.. The remaining water can then be evaporated or mixed with Sodium Chloride to make for a nice, balanced nose spray :D
