new method increases yield and the elimination of water increases reliability
by flash boiling the absorbed water in the tobacco, I have seen increases in total yield from the tobacco of greater than 25%. But, even more importantly, the elimination of H2O from the oil, and subsequent fine filtration/settling of the oil to remove (now) undissolved sodium carbonate... -

pH of unflavored nic liquid?
I meant no immediate obvious general negative reactions, as in the medical definition of acute symptoms. No subacute either that I noticed. as for chemically acute toxicity, I wouldn't know, and would have had no reason to suspect such with acetate. Hence, I asked. I'm still unenlightened... -

pH of unflavored nic liquid?
care to share your reasoning why this would not be a good idea? I've vaped a lot of nicotine acetate, as well as other salts... citrate, malate, tartrate, chloride, etc.. and have experienced no negative acute effects. If you are aware of any potential chronic effects, please enlighten me! :) -

Beta Carboline MAOIs - towards a more effective e-liquid
congrats on your success slopes, and kudo's on the vinegar. I've had 'some' success using it, but for whatever reason the batches are very inconsistent. When I further extract with lab grade stuff, there is much left in the product unaccounted for. I think it's to do with left over base in the... -

Beta Carboline MAOIs - towards a more effective e-liquid
yes, it's a common method in labs TomCatt, as you know. DVAP suggested it just a few pages back. post# 542 "Perhaps the ultrasonic batch would have some advantage but to get the really powerful cavitation and shearing forces going, it takes a high power lab unit that immerses into the... -

Microwave-assisted extraction of solanesol from tobacco leaves
I have taken one new sideline 'experiment' with the initial tobacco preparation that I hope will dramatically increase the extraction efficiency of the alkaloids from the tobacco matrix. zyxel-nsa210.lilu2.ch/MyWeb/public/.../Q10%20in%20solanesol.pdf discusses the Microwave-assisted... -

Beta Carboline MAOIs - towards a more effective e-liquid
I'm still burning through this pound of tobacco, taking careful measurement's and quantifying each of my steps along the way, making one change at a time. (eliminating Easter egging as DVAP put it) One I have a consistent, quantitative end result that people can repeat as written "safely" and... -

secondary extraction to the tobacco with excess water
I added an additional 50ml of basic water to the 'already extracted' tobacco, and let it sit for 5 days. Partly to ensure that the water was taken up, through the oil coating everything, but mostly because of lack of time to get back to it. The water was taken up quite readily, and the tobacco... -

initial extraction of alkaloids from minimal water tobacco charge
I finally got around to extracting and concentrating the alkaloids from the 20g of tobacco. I used a nonpolar solvent with a known high partition co-efficient 3 times on the tobacco, washed the resulting solution 3 times with 1/2 volume of basic water, then extracted to acidic water, washed... -

Comment by 'tceight' in 'protonation of initial tobacco charge.'
Hi rolygate. I have seen that forum area. This intent of this method is different, in that I am attempting to extract both nicotine and the minor alkaloids from tobacco, while getting rid of all the other 'stuff'. Extracting into VG seems to be done mostly for flavour, and bring with it a...- tceight

correction to previous post.
doh, should read "de"protonation throughout, not protonation. That comes later. -

protonation of initial tobacco charge.
a couple days ago, I added 10ml of basic water (78g/l sodium bicarbonate solution pH 12.3) to 25grams of finely ground tobacco and left it in an enclosed container. Today, on opening the container the entire mass was barely moist with a strong earthy smell of ammonia, and the tobacco has gone... -

Kitchen WTA method ---------minimizing initial basic water volume
my reasoning to reduce the initial basic water volume is to maximise the transfer at a 'poor' partition coefficient of 4:1, thereby increasing overall yield. if you use 40 ml of water and 40 ml of oil, then the most you will get is 75% transfer. if you use 20 ml of water and 40ml of oil, then... -

Beta Carboline MAOIs - towards a more effective e-liquid
:-S I was arguing the point that the -OH would be throughout, "The -OH ions will not reach parts that are not wet." not the yield! which is obviously 'better' with LESS water, which has been the point all along. You are saying 'enough to make it wet', and I'm saying that is far too much. I... -

Beta Carboline MAOIs - towards a more effective e-liquid
that is once again, the point. minimize water volume. so what the heck were you arguing about? and it's also the point to THIS. Problem here is defining 'wet'. in my OPINION, 50% of the total mass being water, is soaking wet. That would be adding at most, 10 ml to 20 grams of perfectly... -

Beta Carboline MAOIs - towards a more effective e-liquid
not hiding anything. using the same units as above for clarity. let me be more clear........ using the numbers above, you can dilute the saturated solution 78 times! and still be above 11 pH. 4ml in 10 is only 0.4 times, so yes it IS insignificant. I'm addressing the point I made, regarding... -

Beta Carboline MAOIs - towards a more effective e-liquid
I've always aimed for 11, something I read somewhere at some point. 9 is 'enough' and 10 is lot's according to the experts. more to the point, that very little is needed. I did. You must have missed this in the middle of the post. "assume 20 g of tobacco at a moisture content of at average... -

no, it doesn't it releases C, and creates sodium carbonate. yes, you are missing something, but my fault. This blog was only intended to be a repository of personal posts to make them easy to find again for linking. lipoid pneumonia has been discussed in this thread as well. We are not vaping oil.- tceight
