Tek
Cyb’s “MAX ION” tek
Source
MHRB
Solvent
Naphtha
Reagents
Glacial acetic acid diluted to 6%
NaOH
NaCl
Procedure
Cooked 100.7g MHRB in 500mL water for an hour.
Freeze/thaw three times directly into the extraction vessel (took aprox 4 hours to freeze every time).
Added 104 mL of acetic acid, eight hour cook divided into four 2 hour cooks, waited half an hour between each cook.
Added 300mL of water with 82g of NaCl, and then added 700mL more of water.
Added 46.2g NaOH, dissolved into 100mL of water. Heated for two hours, allowed to rest for one hour after heating.
Pulled 8 times with naphtha between 45-55ºC.
Put in freezer for freeze precipitation, left it there for 18 hours.
Dried, and scraped impure product, 2.3g approx. Recrystallized all the product.
Freeze precipitated, separated dried crystals, and evaporated the rest of the solvent.
Scraped product. 0.6g of white fluffy crystals and 0.4g golden wax.
Notes
All heat baths were done in water at 45-55ºC. The temperature was controlled everytime, and stable. Did the same with naphtha.
Things to improve
- I wonder if I should have done the freeze/thaw step in a plastic bottle. The extraction vessel is a 2L borosilicate jar and costs to freeze it, and it also needs lots of space in the freezer.
- Have to keep in mind that 500mL of water is a lot for the first cook, will be difficult to handle next.
- The vessel, although being perfect for the cooks, has a big downside, it is very wide, and when naphtha is added, the solvent layer has 0,5cm, and it’s very difficult if almost impossible to collect the last 0,25cm without sucking basic soup, which impurifies a lot the product.
- Have to start the extraction in the morning, as if not one has to be various days staying up late, which at the end exhausts a little bit.
Please feel free to do any criticisms, suggestions, or comments.
Would like to thank all the Nexus community, all the people whose posts answered the huge amount of doubts I had, to Cyb and CTM for making the tek, and to the kind people of the chat who helped me with the problems and doubts that appeared when doing the extraction. This would have not been possible without you.
