Hello!
I wrote in another Thread some time ago that I simply cannot filter Harmalas - making the complete process impossible.
The problem:
When I grind the seeds with my (smoothie) mixer some parts of the seeds get crushed ultra fine. When I cook them I get a soup which is extremely full of sediment.
This sediment shall be filtered off - because then you want your Harmalas to precipitate (by adding salt or lye or however you prefer).
Therefore this soup can't get through a filter. I used a towel to filter it - which is not really useful as it's like not filtering at all, but at least some stuff was removed.
Now I started to add salt and it precipitated. Then I tried to filter that off - no chance.
Then I said: Ah ... then I'll add the lye and get the freebase harmalas, possibly they will be easier to filter.
But also not - I even used a MOTORIZED LABORATORY PUMP, which is insanely strong and a Büchner Funn el with 15 cm diameter. I got like 100 ml of my 2 liter soup filtered within 5 hours with this. Therefore - NO!
So my Idea is now: As it is impossible to filter it, I'd just extract the already-precipitated freebase Harmalas with an unpolar solvent. But what Solvent could I use ?
The Harmalas are already precipitated and not in the salt-form anymore. Therefore they should be jumping into a non-polar solvent in no time, when I put them together.
But now I used:
- Toluene
- Dichlormethane
- Ethyl Acetate
- Diethyl Ether
And all I got was that the organic layer got a liiittle bit coloured, but you could still see through - and the Harmalas were still sitting precipitated in the aqueous phase ...
I really don't know what I can do anymore, it's such a shame because I got such huge amounts of Harmalas I guess, as I used like 700 g Syrian Rue : /
I can see them so near and cannot get through them ...
2. Would it be possible to evaporate the water in an oven ? Yeah ... the NaOH will remain there ... but then at least I'd get something. But if I do the temperature of the oven to 80°C - will that kill the Harmalas ? Well in Solution - when doing the cooking - not ... but then they are unprotected lying at the air - I guess the oxygen will make short work of most of it, making it inactive ?
Please help me to get my Harmalas : S If this batch is working, I'd never have to extract them again. *sigh* =P
