Introduction
The CIELO mescaline extraction TEK acronym stands for Crystals In Ethyl-acetate Leisurely OTC (Over The Counter).
The TEK is simple: aqueous cactus plant matter is broken down by microwave radiation, saturated with NaCl, made alkaline, and extracted with ethyl acetate. The extract is dried over MgSO4 and crystalized out of the solvent using citric acid.
Materials
- Quart jars and lids
- Food scale
- 100g powdered dry cacti
- 25g Ca(OH)2 (lime)
- 300g water
- Microwave
- 100g NaCl (plain table salt)
- Ethyl acetate (sometimes labeled "MEK substitute"
- Anhydrous MgSO4
- Paper filters (optional)
- pH paper (optional)
- Shallow baking glass dish and lid
- Citric acid
Safety
Ethyl acetate is a natural product in small amounts in some foods and fermented beverages. It is volatile and the smell can be strong. Work in a well ventilated area and keep lids on as much as possible. The fumes smell sweet and usually dissipate quickly. Read the safety information here, and check your manufacture's MSDS to verify you have ethyl acetate without additives such as methanol. Test all plastic you are planning to use with ethyl acetate and make sure it does not degrade. NEVER pour ethyl acetate down the drain. Not only is solvent in the water an environmental issue, but ethyl acetate can damage PVC pipes. Do not have an open flame anywhere near ethyl acetate. After searching for and reviewing the safety information it is up to you to make an adult personal decision on using ethyl acetate.
These are only good-faith safety tips. They do not guarantee safety. Each adult individual needs to make their personal decisions on how/if to use over the counter chemicals.
Process
1 Paste
Slowly add cactus powder to water while stirring to form a homogeneous paste. Microwave in short bursts monitoring closely (paste will swell quickly) and stir between irradiations until (1) color changes from green to tan and (2) at least 75ml of water evaporate. After both of these conditions are met, mix in NaCl and Ca(OH)2. The ideal paste is stiff and not hard to stir. If needed, adjust consistency by adding a little water (runnier) or lime (stiffer).
2 Pull
Add ~ 300g of ethyl acetate (fill the jar about 3/4 full). Extract for a few hours shaking vigorously every once in a while*. Decant solvent into second jar. About ~ 50g of solvent will remain in the paste (the pulls are still very efficient despite this). Pull two more times with ~250g of ethyl acetate. Combined pulls will give about ~750g (~0.9 quarts) of clear yellow extract.
*If solvent separation is poor the starting paste was too wet. Fix by adding lime to release solvent. Released solvent will be clouy due to suspended lime and will clear up.
3 Dry
Dry extract with anhydrous MgSO4 (3g of drying agent per 100ml of extract should be plenty). Settle and decant/filter clear solution into a shallow dish.
4 Salt
Gently drop citric acid into the extract without stirring** and cover. Clouds form as the citric acid dissolves by diffusion. After a few hours the clouds settle as beautiful citrate xtals.
Progress can be monitored by cloud formation: salting is finished when no new clouds form after adding more citric acid. Alternatively, pH paper can be used, salting is fine finished when neutral or acidic.
Over acidifying is not a concern as long as citric acid saturation is avoided so it can go into solution. However, there is no reason to get close to saturation, a few hundred mg of citric acid should be more than enough.
Every 10mg of citric acid (CitH3) reacts with enough free base mescaline (Mes) to precipitate up to 43mg of mescaline citrate:
**Stirring won't cause any major issues but xtals will be smaller.
5 Finish
Pour off ethyl acetate into a storage container*** using a coffee filter to help pick up any loose xtals. Rinse xtals with anhydrous ethyl acetate until yellow color is removed to personal cosmetic satisfaction. Leave xtals uncovered to evaporate all residual solvent, this is the final product.
Mass spec results are current pending. Hopefully they will show the product is mescaline citrate within measurement sensitivity (already >98% pure) even when not completely white after two rinses. Yields are highly dependent on starting cacti powder and can vary from 0.1% to 5% (0.5% to 1% being common).
***Solvent should be washed with brine and reused.
