Just a quick question...how clean does the pseudoephedrine have to be... like completely glass needles for the RP/I to work... I have ran this couple times with fairly pure pseudoephedrine and very pure iodine and red p and it fails...im guessing there's still a little something on the pseudoephedrine

 

[G.Patton]

I can't answer accurately. It should be pretty pure.

 

[waltjr5858]

Also temperature for the reaction 60 to 80c is that enough? 24 hours? Will too much water cause a failure by making the mixture less concentrated?

This post about extraction. Please, write me in DM your questions about synthesis with more details.

Čo Cirrus obsahuje
- Účinné látky: - Zložky, ktoré sú v prípravku Cirrus obsiahnuté:
Každá tableta obsahuje 5 mg cetirizín dihydrochloridu vo forme s okamžitým uvoľňovaním
a 120 mg pseudoefedríniumchloridu vo forme s predĺženým uvoľňovaním.
- Ďalšie neúčinné látky:
Hypromelóza.
Mikrokryštalická celulóza.
Koloidný oxid kremičitý bezvodý.
Stearan horečnatý.
Monohydrát laktózy

pdwshopnl, vo všeobecnosti váš spôsob extrakcie vyzerá dobre. Forma s predĺženým uvoľňovaním - a tam je obal tabliet. Pred extrakciou toluénom je potrebné všetko rozpustiť v teplej vode, odfiltrovať od nerozpustných a po už extrahovaných toluénom.

Anyone that come across magnesium stearate in their pills....initially extract with very....very cold methanol and each time allow it to sit after stirring unless all the crap settles and pour off there clear methanol... repeat 3x. Combine and put in freezer to crash as much wax as possible and stearic acid... then add take methanol and add 15 % water and add HCL in the amount of 6% of your solution... heat to 50c no more for 1 hour... this will hydrolyze the magnesium stearate to stearic acid....it has to come out trust me. After one hour raise temp to 60c and reduce volume by at least 50% and put right back in freezer and keep it in there for 2+ hours... you will see a cloudy solution with chunks floating on top... success. Now take a little glass funnel and stuff tightly a piece of cotton in the neck... it will filter very slow but crystal clear. Don't add all to funnel at once and keep putting back in the freezer in between. Once all filtered under LOW heat reduce volume until it starts getting yellow and when you smell the steam it stings your nose.... its sublimation. Back in freezer get very cold which at this put they are probably crashing out and filter pure fluffy crystals...

 

[waltjr5858]

Oh I completely forgot to add one of the most important things after the hydrolysis is complete the 1 hour you want to add a little more water to make the solution more polar because now you're going to add a nonpolar that you do not want to mix with the water methanol mix which is meant to extract the stearic acid that was present and the magnesium stearate you converted to stearic acid... because both are typically present. Extract three times then start reducing volume of water and methanol towards crystallization and crash with acetone if need be.

I think it should be possible making meth without crushing the Iodine out by adding sodium thiosulfate, but of course probably the product could be not from the highest purity. But I never tried it this way.

Just to give my 2 cent's to the Pseudo-pill extraction:

I was using pills containing 60mg Pseudo and 2,5mg Triprolidine each.
I started to extract all the stuff 2-3 times with denatured alcohol and after drying I first did an 12-15h xylene soak under periodically stiring. After that I washed the Pseudo by cocking it 3 times in fresh toluene for 10 minutes under magnetic stiring and good ventilation.
After filtration and drying I recristalized it in an mixture of EtOH and some water and the product was pretty clean and good precursor for making Meth via I/RP.

All solvents were dried with molecular sieves before use.

you know if it's the Czech way it can be! in 40 minutes it's done the Czech way. 1 ephedrine, 1 iodine and 0.3 red phosphorus with the expected amount of finished product if you wait for 6 grams but from 10 grams of ephedrine you put 6 cubes of phosphoric acid. lately they put something in the pills and the iodine comes out more difficult as well as the degrees are a little higher and now I have to blow with a hose to get the iodine out. your question after straining can be use the red phosphorus with a little new. acidification with hydrochloric acid ph13+ with sodium hydroxide or packets for unclogging channels for hot water! after straining you put one to three. you expect 10 grams of final product you put in a little water and three cubes of hydrochloric acid. personally I calculate it at 60% compared to ephedrine as the final product. Yes in some cases depending on pills or injectable ephedrine it can reach 80%, but I calculate it at. 60 so it doesn't turn sour.

Can someone explain this to me? The video differs slightly from the written recipe. I need the measurements for all the ingredients for the entire process.

 

[William Dampier]

The difference in quantity can only be due to the excess of iodine used in the method. The amount of other reagents depends on the calculation of the iodine excess for ephedrine. It’s better to use a sufficient excess in case of evaporation what’s indicated in the text is enough.

I have a medication containing 60mg of pseudoephedrine and 2.5mg of triprolidine. Will this affect the extraction of the ephedrine, and how can I remove the 2.5mg portion?

 

[thruster]

Simply do the extraction and the workup like I wrote on this thread:

Grind the pills and extract 3 times with denatured alcohol. Do a 12-24h soak in some nonpolar solvent like Xylene (with occasionally stiring), after that wash with cold Acetone. Then wash it by stiring it for 10 minutes in hot/boiling Toluene(GOOD ventilation!). Repeat with fresh Toluene until the filtered solvent is free of yellow/ brownish color (3-4 washes in total). After that dry, wash with ice cold Acetone, filter, and do recrystallisation from hot IPA or Ethanol or Methanol or some mix of this solvents.

Relating to the pills you use, with this method you will get very clean Pseudo which will work great for reduction.

 

[thruster]

And always use anhydrous /dried solvents. For me Molecular sieves 3A and 4A are working best.
