bubbly naptha

[charliewired]

someone told me he noticed when he placed the very hot naptha into the bottle also hot and upended it 3min, it was very bubbly after it settles 10-30 min with sort of brownish foam suspended within it. Did he shake to vigorously? Are the solvent or the bottle containing the solution not hot enough or too hot? Did he do something else wrong?
Any ideas?
Cheers

PS he may have let a little bit too much sediment through the stages. But its his first time.

That foamy stuff is called an emulsion and if it doesn't clear it could be your PH wasn't high enough?Check your PH and make sure it's at 13.4.I do assume yo're doing a MHRB extraction right?I put the bottle with the solvent into the crockpot after upending and it usually clears in less than ten minutes.

i'll tell him

It didn't turn black until the last ml went in? well there's your problem buddy your PH is too low.when it turns black you're supposed to add another 10 - 25 % more lye solution to make sure your PH is up there.Siphon off your naphtha,add more lye check PH to be 13.4 and put back the same naphtha and you shuld be alright.Don't you have a PH meter?

the bottle didnt turn black untill the last ml of the 100ml went into the bottle

Sounds like you hit pH 12 not pH 13 to me. Check with a pH meter to be sure, then maybe add some more lye, carefully.

Another option is to just wait several hours, thats the usual way to deal with emulsions..

Oh - Quantumbrujo was quicker at replying, hehe....

(he's right about adding more lye I think; but you can leave the naphta in when adding more lye, it doesn't do any harm)

thanks

Weigh your result if you have a suitable scale. Check if the yield is more or less what you expected.

To check if no crystals are left in the naptha, let it evap. down to maybe 25ml or so and stick it back in the freezer to see if anything else precipitates. After that you could always try to let it evap. completely.

To check if you basified enough and extracted everything from the aq. extract, add some more NaOH sol. (too much is probably much better than too little) and extract with some fresh naptha. Repeat the extraction with some fresh naptha if you still aren't sure you got everything.

I don't think naptha should evaporate much when extracting under normal conditions. Perhaps try using a closable container, but you may have to vent periodically to release pressure build-up (esp. when heating).

I think the crystals sticking to the sides and bottom is normal. I think after the "snowstorm" the crystals will settle down and stick to the glass.

So Charlie,how did it go? how much did you yield?don't expect to get a whole bunch.MHRB is average of about .5% DMT.but there's been some killer bark lately at almost 1%.All depends on the quality of the bark and the extraction.For your first time if you get >.4 of a gram you should be happy.that's 8 good journeys to the other side.Are your crystals nice and white or are they slightly yellowish?

1 Tablespoon of Lye is added to 100ml of water = pH 13.4
This solution is then added to the HOT acidic extraction,
it'll first turn whitish - grey, upend the bottle untill it turns All Black in color.
