Understanding ph in Mescaline extraction

[cyantific]

Everything I've read indicates that mescaline precipitates out of solution best at ph range of 6.5-7.0.

My tap water is around ph 7, so the addition of acids (vinegar or HCL) drop the ph way lower then the recommended range for mescaline to drop out of solution.

I've been using 69rons tek. Is there something I'm missing?

Thanks for any guidance you can provide.

yea....saturation point.
there needs to be a high enough concentration of mescaline salt in solution for it to "crash out", or lower the solubility by adding another solvent which it will be less soluble in. I suggest adding acetone to the water (60:40 acetone:water), then freezing it

 

[cyantific]

So rather then vinegar, add 60:40 acetone:water to the limonene then freeze instead of evaporate?

you are talking about the salting step, benz is referring to a purification step that happens after you've removed the mescaline from the non-polar solvent


some thing like this:
you have freebase mescalin in d-limo
you add ph 7 water to the np and mix, the water layer's ph will rise as is absorbs the mescaline
it doesn't precip out
now, add small drops of very dilute acid to the mix, shake and test ph until the waters ph is back down to ph 6-7
remove water layer, evap or use a "dual solvent crystallization" which works better with some salt forms than others

thanks dg. So we're simply salting the mescaline with ph adjusted water, and very little acid is required. 69rons tek calls for way too much vinegar, resulting a ph of 3.0

In a previous extraction I added baking soda to bring the ph back up. Do you guys know of a way to remove the sodium bicarbonate from the final product?

^ easiest would be to let your stomach do it

 

[cyantific]

I'm trying to figure out how much of my final product is sodium bicarbonate. Is there something sodium bicarb is soluble in but mescaline is not?

Also, if using calcium hydroxide, what's a good ph for the base?

Thank you!
