mescaline degradation from air exposure?

I have a quick question about a mescaline extraction i've been working on for a few weeks now.

After adding xylene to my cactus solution, i used 4 drops of 30% muriatic acid to 1 cup water and added this to my pulled xylene. After freezing, i dumped out xylene back into the cactus solution and poured my acidic solution into a baking dish after thawing and let this evaporate (about 24 hours or so). When i scraped up the crystals, i got a yellowish, tan colored powder which i have let sit out on a separate dish for some time now. I have let this powder sit for about a week now in the open air on top of my fridge because i have continued to add to it from my other pulls (i have been doing about 1 pull a day for the last couple weeks now).

Is there any kind of degradation from letting the mescaline hcl powder sit in the open like that for some time? My house is around 70 degrees, so i know there isn't any kind of excess heat. I also noticed that after i take the xylene/hcl solution out of the freezer, a small amount of xylene always seems to get in the baking dish after i thaw out the acidic water. I figured it will just evaporate out however and shouldn't be a problem. Anyone else have this problem? I looked all over for this type of question but i couldn't find it anywhere, so i hope this hasn't been asked already. Any answers are appreciated
 
The solvent will just evaporate off so it's not an issue. Mescaline is a very stable molecule so you don't have to worry about it degrading while sitting out a few weeks or even months for that matter.
 
great, i thought it would be ok so ive left it out but am doing an acetone wash tonight to clean it up and then store it in the freezer.

My xylene was normal for the first 7 or 8 pulls, with that transparent yellow color separating to the top each time, but recently it has turned a very murky, pale yellow color and is no longer translucent. I'm guessing its because i might have shaken up the bottle a little too hard, but i'm not sure. My first pull with this murky xylene ended up yielding a green powder instead of the yellowish tan i got before, so i'm thinking i might just ditch it. Anyone else have this experience?

to get cleaner end product:
1. the freezeing of the np and salted layer isn't as clean as using a sep funnel, or just careful decanting using suction or pipette. emulsion layers and np are easily filtered out using a funnle and cotton ball
2. thats way too much acid
3. rarely worth it to go past 4-5 pulls ime
 
Yeah the whole freezing thing is completely unnecessary, missed that the 1st time I read your post. You can use a clear plastic bag if you can't afford a sep. Just add the mixture to the bag, let the layers form, and snip the corner with a pair of scissors. Drain the polar water layer and pinch the corner when it gets to your nonpolar solvent. Will be much less time consuming and give better results. Do not throw your green product out. It's green because you didn't defat enough so you know for next time. Take your dirty mescaline and wash it a few times with anhydrous acetone and it'll clean it right up. If you need to know how to make anhydrous acetone from wet look up lajunks thread about cocaine purification, doing the same thing here. Do not use hardware store chems if you plan on eating this, biodiesel companies sell 99.9% purity very cheap so there are no excuses really. If you're not happy with the purity after washing a few times you might want to preform a recrystallization by dissolving in a minimum amount of hot IPA and then precipitating with Et2O or acetone. Should end up with the best mescaline you've ever extracted;)
 
dg420 excess HCl just evaporates off. It is a gas when not in solution you know so that's really not on issue. If you use hardware store HCl you're going to want to clean it anyway though.
 
I've been experimenting with the amount of hcl to use, and after getting a brown product the first few times (probably between 6-8 drops, which is too much i know), i have since lowered it to 4 drops, which gives me the yellowish colored powder now after the water evaporates (i always use 1 cup water every time, and end up pouring it in the xylene to the point where its about 1/2 inch above the jar at the bottom). Maybe i'll only use 2 drops this next time and see if it turns out cleaner.

Thanks for the baggie trick trip, i'll definitely have to use that from now on

yeah, but extra acid pulls colored impurities that wont totally wash away
careful titration is the way to go
 
When using a plastic bag as a sep funnel, work quickly as i'm pretty sure xylene will dissolve polyethylene or polypropylene.
