Plant material was Phragmites Australis roots.
Tek used: Marsofold's (+defatting , as sugested on the site)
. ~400 gr roots cleaned, chopped and grinded
. solution of ~3200 ml tap water with ~600 ml 9% white vinegar was prepared
. plant material was boiled 3 times (50% of solution first, then 25%, 25%) and resulting "juice" collected through strainer
three days later:
. "juice" was mixed with ~300 ml solvent (containing toluene and xylene) and then "shaken hard"
this created a thick layer of what SWIM understood is emulsion
two days later:
.some rock salt added to the jar, slowly stirred and then jar heated reducing the emulsion considerably
.the top layer , which now looked more clear (like the solvent) but still with some 'foam' was sucked up with a syringe and discarded
.the defating step was repeated two more times, at about 15 min intervals, only this time gently mixed with a wooden spoon and not shaken hard
.six Tablespoons of caustic soda granules (drain pipe cleaner) were premixed with ~400 ml water and added to the jar (actually 4 Tbls's initially and then decided to make some more with another 2 Tbls, because the juice in the jar "did not turn black"Wink.
this resulted in some darkening of the light yellow solution from the jar, but it was certainly not black but rther a somewhat brown color. SWIM atributed this to the using of different plant material and not a too low pH, altough he did not have a pH meter.
.~250 ml naphta (Zippo lighter fluid) was added into the jar then gently stirred
.everything was stirred gently, let ~3 hours and then the clear layer was sucked with a syringe and put into a pint mason jar
.pint mason jar with resulting solution stayed 3 days in a freezer (that freezez ice cream hard 8) , so this was certainly not the problem)
.the jar was then shaken and the solution was quickly poured over a funnel into which a filter cofee paper was put.
.after all the solution was strained, the filter did not contain any crystals at all
SWIM waiting for forum members opinions as to probable cause of complete failure.
