Like a boiling chip for boiling, the dust gives the waxes something to precipitate onto. Very interesting. It is a sort of thin film chromatography separation and works surprisingly well for seperating the components of an extract. By re-dissolving their extracts in hot ethanol and then placing that in the freezer overnight, some of the undesirables will precipitate out and may be filtered out. At 250F, there won't be alcohol or water left. I usually make a QWET into your HOA formula, batches of 1-2 ohzees per batch, and so I usually just add the coconut oil, cinnamon oils, etc. I know it has other elements in it... but will these evaporate over time with winterization, or is it too dangerous to even try this method? This doesnt mean it isn't effective it just means that more understanding is gained with each effort. Set aside and come back in 1/2 hour. http://www.coleman.com/uploadedFiles/Content/Customer_Support/Safety/lantern.pdf This is our main concern. The salt, if any, left in the extract is not detectable. Lastly, Hexane is as explosive as gasoline. Oil can leave a dark stain on pavement, but you may be able to clean even stubborn spots out of your driveway. I lit the picture on fire and warmed myself. The hexane/oil remained dark, but though we must have done it right already... We purged - the oil was still black. I shook the mixture well and let it soak for a day to extract the material from the roaches and scrapings, before straining it through a wire strainer and then a coffee filter. what if it is green? Adding salt is not productive at all because it iterferes with the water in a way that prevents the water from pulling pinene out of the goop. For some reason, my alcohol, Hexane and water mixture does not bringing chlorophyll down. It is not correct to say that using hexane is not highly effective at recovering thc from any form of extract. Next month I plan to do a vid from start to finish and present the results in a video to show it. Hexanes dielectric index is closer to 1.3 and for all practical purposes, isn't miscible, so I thinking not. After shaking it well, I hung it from one corner, to let it stratify, and after it had, I clipped off the lower corner of the Ziploc bag, and by pinching it, and controlling the bleed rate, I was able to bleed off the water, alcohol, and emulsion layer, so that only the now gold hexane solution remained. Following this I dissolve the winterized oil in n-hexane (Ratio 20 g ISO to 100 ml hexane). ;). Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value. After removing the hexane, you can winterize with Ethanol to remove the plant waxes, and help purge the remaining hexane. I wring the tea bags and am left with white waxy stuff and other solids. There is a SURE fire way to remove the polar substances from your extract, and furthermore purify your compound to either a pure cannabinoid product or nearly pure. The web says PAM is water soluable. correction - "condensation nuclei" (it has been decades since my meterology courses in professional pilot school), I'm pretty sure I get the picture, but question whether you do or not brother/dude/man, as well as your intent in wording your input. Cite. I am working on cereal prolamins, and to isolate them, I have gone through the literature available where the protocol includes the step "defatting" but nowhere it is described. https://vimeo.com/181396690. The water layer underneath was clear. Do you have an email graywolf? GW. I suggest to flush the remaining lipid obtained after evaporation with nitrogen to ensure removal of hexane. How to remove hexane from a extracted essential oil sample ? In Flash Chromatography you NEVER let the column go dry or it fails the column. It has extremely low volitility. without seeing the stuff.... I only have one video which only shows one step and how effective the process works just as a pure filtration method rather than seperation. I have a half pound of green wax, Maui Waui, it's orange when looked at in the light. Good luck. Make sure your work area is dust/contaminate free. What would happen if you put an oil extract through a reverse osmosis system? I have found that when holding a flame to bubble the puddle the bubbles will mostly stop after short time and the puddle "settles down". Salt water washing uses a separatory funnel as above, but we start out dissolving the extraction to be cleaned directly into hot n-Hexane, and then washing the hexane solution with saturated salt water. I came across a problem with onion extraction in ethanol and I ended up with a pasty mass.
