Question I have a question about amph base/oil to sulfate

[mathias450]

Hello,
how is practicaly made amphetamine sulfate from base if we have sulphuric acid and isopropanol. does this process require an increase in temperature (cooking)?

Hi,

No, mix the sulphuric acid with ipa 1:10 and acidify the amphetamineoil whilestirring until you reach pH 6.

Then vacuumfilter, wash with cold acetone or ipa and dry.

Voila

Hi,
So the first thing i will do when i reach a 6 pH is vacuumfilter?
Excatly what kind of vacuumfilter is neccesary.
Thank you very much for answer.

When you have acidified your amphetami oil it should be like heavy cream.

Cover it up with a plasticbag and rubberband and put it in the fridge or freezer.

The day after your vacuumfilter it using a buchner funnel with a medium < 10um filter.

When you have drained the liquid your pour preferably cold acetone 99% > or IPA 99% > to wash the amphetamine.

Once you have drained all of the washing put it in an open container and inside the freezer.

The cold wash will evaporate slowly and the amphetamine won't oxidize as fast as it would in a room.

Once it has reached desired dfyness vacuum seal it.

Best regards

Thank you for informations.
So when i acidify oil i will put it in fridge where it mustn't have contact with air for 1 day and they vacuumfilter it.
How excatly is it washed and why. Can i use acetone in start when i acidify the oil?
Greetings.

Yes, when you are done with acidification you put it in the freezer, the reason is because the liquid becomes more dense, and wont precipritate as easily through the filter resulting.

You will notoce that the liquid from the reaction will firstly be vacuumed out, but you don't want it completely dry.

Then you just take cold acetone and pour it straight over the amphetamines while the vacuum is running.

You wash the amphetamine to clean it from any remaining impurities from the reaction.

Both acetone and ipa are good for this, reason for acetone over ipa is because it evaporates twice as fast.

Best regards

But if i use acetone in start, will i make a same ratio (1:10) like i am doing it with ipa?
Thank you.
Best regards.

Yes

Hi swim uses the following method

1 liter a-oil(freebase)
2 liter methanol

Stir until properly mixed
Than add sulphuric acid 50% until it stops precipitating out.

Once it stops reacting put it in the freezer (important to get a good structured paste)

Add acid slowly as it will heat up due to the reaction and closely monitor ph towards 6.

In case u lower the ph to much u can correct it with more a-oil.

Also bear in mind the finished product reacts with oxigen and its best to keep in a alcohol solution and store it as paste.


Choose a solvent with a quick evaporation rate as it will take forever otherwise.

Good luck
