First extraction, a-nitrile-ated...

[dooby]

Hello,

My first ever extraction on 100 gr of powdered mhrb was reasonably successful with room-temperature precipitation on pulls 1 and 2...

I am afraid, however, that I made a mistake and I am not sure if this will affect the quality of my yield and, if so, how to resolve the situation.

Being very apprehensive about the base/naphtha mixture touching any plastic or aluminium I came up with the idea to wedge one of my disposable nitrile gloves between the bottle and the cap which seemed to work like a charm...

After every shake/roll, said nitrile glove was removed from its position, rinsed and put aside until the next shake/roll (during separation bottle was "capped" with a small glass disc),

At the end of the day, no visible damage to the nitrile itself but I did notice quite a bit of discoloration (used to be blue, now a blue-ish white)...

My pull jar is still in the fridge and will remain there until no more crystal formation is noticed...

How should I proceed?

The tek I used was more or less Cybs hybrid salt tek...

I have never bought fumaric acid but I was under the impression it was sold as a food additive/suppliment. You might want to check your local health food store instead of the pharmacy.

This is starting to sound WAY more expensive than starting again with new material but I'm definitely learning some.

Starting a new extraction would be easier, cheaper and less time-consuming but on the other hand this was my first ever yield so trying to save it is not only a matter of priciple but it's also fun and educational...

As long as you're having fun go for it buddy, I'm just amazed at your persistence lol..

Also, search for VRP fumaric, should help with your psoriasis problem.

It's doubtful there's any nitrile in your solvent, Dooby - nitrile rubber is quite resistant to naphtha. That's partly why it's been made into a glove.

As Benzyme says, a bit of the pigment (a tiny amount) has dissolved into the mixture and a simple recrystallisation would, in my opinion, suffice to clean that up.

The cleanup with activated carbon and ethyl acetate sounds like fun (but I am a total nerd); activated charcoal pellets can be obtained for aquarium filters and it's not that difficult to make your own ethyl acetate if you really wanted to... or maybe just use 96% ethanol instead.

My 100th post! And it only took 5 years!
