Are these the things I need to look up? I'm not having great luck so far. What is the brand name of the solvent you use? ACGIH and OHSA are American chemical safety regulators TLV - threshold limit value PEL - permissible exposure limit PPM - parts per million "Laws alone can not secure freedom of expression; in order that every man present his views without penalty there must be a spirit of tolerance in the entire population." -Albert Einstein

Contains 99.9+% light aliphatic hydrocarbon, also known as light naphtha (low boiling non aromatics with 5-8 carbon atoms) "Laws alone can not secure freedom of expression; in order that every man present his views without penalty there must be a spirit of tolerance in the entire population." -Albert Einstein

Light doesnt exactly sound like what I'm looking for but to be honest I'm having a hard time finding out what exactly I'm aiming for in my naphtha content. Can you shed some light on this? Is what I have a desirable solvent for dmt extraction? The only thing I've been able to gather is that I want aliphatic and not aromatic.

Light is exactly what you need. Don't forget to process an evap test to be sure there is no residue. « I love the smell of boiling MHRB in the morning »

Is what I have a desirable solvent for dmt extraction? The only thing I've been able to gather is that I want aliphatic and not aromatic. Petroleum naphtha is split into light and heavy fractions during the refining process. Light naphtha boils between 30C and 100C, while heavy naphtha boils between 101C and 190C. You want light naphtha for DMT extraction as it contains fewer different hydrocarbon structures and very little in the way of cyclics.

yessir, that is basically vm&p naphtha, aka light naphtha. "Nothing is true, everything is permitted." ~ hassan i sabbah "Experiments are the only means of attaining knowledge at our disposal. The rest is poetry, imagination." -Max Planck

OK, i wasn't too good at chemistry... Is Ronsonol a good choice, or should i go with something like ACE VM&P Naptha from the hardware store? I don't understand these charts at all. I wish someone would just say "use this"...

For what it's worth, it says these runs were done in 2005. Many of these products may have changed their formulas up significantly since then (I know Klean Strip has a few times).

Hey I looked up the msds for a lighter fluid and it says petroleum distillates and hyrdotreated petroleum distillates. What is this and is it safe to use?

I just typed in "naphtha canada" (you need to spell naphtha correctly btw) and readily found lots of posts with information. Some recent threads are: Is this Naphtha ok? Substitute for napthaWhat lighter fluid or alternative?Good luck.

I'm just trying to get a more recent answer. As you know, things can change. Even in the links you provided some people are saying Ronsonol no longer works and Zippo lighter fluid has changed their recipe.

hello i have tryed 2 extracction wth the sae naphtha, andwhen i hoing tp eveporae, it never get fully evaporated. it always get like a brown fat snd never gets clean or dry. i thinking culd be becouse thhr kine of naphtha i uin. im reading nowth componets in it , adsa it has hydrocarbons and c9 aromatics coukd anybody help me ? thanks Alberto

Ive been perusing https://www.sherwin-williams.com/, and they seem to have several different high flash Naphthas. Such as Sherwin-Williams High Flash Naphtha 100 R2K5 and Sherwin-Williams High Flash Naphtha 150 R2KT4How would these differ from VN&P? Are they more or less useful? Thanks H.Billy

Strangely they just offer product details to the 100 version ... but the following aspects apply to both and I think you should not use both for this reason: They are only aromatic Hydrocarbons and not aliphatic Hydrocarbons. Aromatic means, their electrons have a different hybridization and binding condition. They carry an additional form of electrons, called P-electrons. These can induce much higher Van-der-Waals binding forces and therefore these aromatic solvents are regarded as much "stronger solvents". This means that you will never be able to freeze-precipitate anything with them. Also because of this you will catch up a huge amount of unwanted compounds. Being inable to freeze-precipitate you would always have to fully evaporate your solvent - which is possible of course, but you will always be left with a goo and maybe only 50 % of this will be DMT. Not only purity is an issue, but also sticky stuff is always a nightmare to handle. I'm not from the US so I never was into VM&P Naphtha, but I think it has only aliphatic Hydrocarbons, which have the correct solubility profile to selectively dissolve mostly only DMT and also drop it at -20 °C in the freezer. No reason to go for another product. Then you also should take an eye on the isomer size (the size of the single molecules that are sold as the solvent). The perfect range is C6-C7, meaning isomers of Hexane and Heptane. They have the perfect solubility profile and are also the best for freeze precipitating. As stated above that 2 solvents are not useful due to their aromatic nature, but also they have "too big" molecules, being a mix of C8-C10. The boiling point is much higher because of this (135 °C - 210 °C) and this is always a good way to quickly check if you have the correct mixture. The max boiling temp (upper end of the temp range) would be not higher than 100 °C if you have the C6-C7 mixture. Even if you have aliphatic (and not aromatic) hydrocarbons, therefore being the correct chemical family, you would get a bad solubility profile and not be able to freeze precipitate, if you go to a high boiling point range, so also keep an eye on this. C6-C7 is the way to go.
