Methylphenidate extraction step by step/ help?

SWIM is in the process of a Methphenidate extraction using isopropyl alcohol. SWIM is wondering if the steps he's taken so far have been correct.
1) crushed 1,000 MGS of Ritalin to fine powder (it was white)
2) added approx 50 to 70 MLs of isopropyl alcohol
3) shook vigorously for a few minutes
4) after about 10 minutes the mixture turned slightly yellowish and impossible to see through
5) after about another 10 minutes the mixture turned extremely yellow but "see-through"
6) the yellow alcohol/hopefully Methylphenidate mixture was removed via a syringe
7) more isopropyl alcohol was added to the white gunk at the bottom
8) the mixture turned yellow again (meaning it takes a few pulls to extract all the methylphendidate maybe?)

Now thats where I am at so far, im gonna try a few more pulls and then evaporate the yellow liquid using a fan or hairdryer.
can anyone add any helpfull tips or can confirm i am doing it right? thanks in advance

use denatural alcohol 95% to extract, than evapourate and than do an ab extraction, than do a re-x, swiy definitely will have pure hcl.

lovelyuy added 424 Minutes and 20 Seconds later...

And don't use isopropyl alcohol for the extraction. if swiy don't know how to do an ab extraction, after the solvent extraction, freeze to semi and than filter, this will remove the wax

thanks for the input, SWIM actually finished and got left with a half or a little more of a gram of yellowish powder, it actually worked great but next time SWIM will try with denatural alcohol, thanks.

Re: Methylphenidate extraction step by step/ help?

My poodle read in a magazine a while ago that when Mr. Spock tried this with 96 proof ethanol, he did get a yellow liquid, however the pill mass at the bottom turned into a gunky mass. In the subsequent interview, he stated that this might have been due to some of the green-grey time release part of the concerta pill having dissolved in the warmed ethanol. Can any of you verify Mr. Spock's statement?
