Question Amphetamineoil consistency

[WinterDust]

Hi,

So I did a little experiment yesterday.

I open distilled my amphetamineoil, what I meam by this is that.

I poured my amphetamineoil into a large beaker, put it under a fumehood and started distilling of the ipa.

Boilingpoint started at ~84c and when it went above 90 I stopped then all of the ipa had evaporated.

My question is, the consistency of the amphetaminoil is like suryp and very sticly.

The color changed from bright transparent yellow to very dark oak whiskey.

Would anyone with first hand experience with vacuumdistilled amphetamineoil say this sounds about right?

Best regards

You're probably referring to the dirty amphetamine base in isopropyl alcohol.
If you took out the ips+amine after the reaction and just evaporated the ips, you have a dirty base.

Of course, if you received amphetamine salts, then most of the dirt remained in alcohol and acetone wash.

To get a distilled base, you need to distill the base fractionally. Amphetamine oil can be distilled with water vapor.
If you don't have accurate fractional distillation equipment but want to get a clean oil with close to 100% amphetamine content, then you need to dissolve your dirty oil in water and make the PH level 5,5-6 and rinse with a non-polar solvent. Then alkalize and select the oil, extract and evaporate the extractant.
Combine all the oil and distill with either water steam or vacuum.
Why do we do acid-base extraction?
Since your base contains not only amphetamine oil, but also other oils that will be distilled along with oil A, you will end up with refined impurities and some amphetamine and the composition of the oil will not correspond to the desired purity.
The purest amphetamine base is an almost clear oil with a slight fishy odor.
All other odors, if present, are decomposition of the product or impurities.
Do not store amphetamine oil in the air, in the air it oxidizes to carbonate.

I double what Hank said about colour, it took me quite some time to arrive at a relatively pure Amphetamine distilling the oil twice, and the colour is white/transparent. I can`t even find any yellow in it.

For distilling oils short path is great, before this I used an air-cooler, as room temperature is more than enough to condense the vapours of oils. The bigger the equipment the more losses, unless of course you are doing kgs of A-oil. Just an example of the waste, once I distilled about 40ml oil from a 1l flask, emptied it as much as I could to the last drop and thought I could rinse it with some acidic drinks no to waste the oil stuck on the walls. I drank about 1/3 of it tops and I had a very strong rush, basically too much in every sense of the word.

@Hank Schrader

Thank you for the answer, very elaborated, I appreciate it.

I have access too fractional distillation with vacuum, but I accidently broke my Liebeg-cooler, so I'm waiting for a new one.

Reason for this is that I wanted to see what happens if I would distill in an open container, in comparison to vacuum distilled.

Best regards

Are you using a Liebeg with a vacuum claisen at the end? If yes your collumn length may be too big.Volatile oils distill well under short path.
