Naphtha cannabis extraction

[Nagappa]

What brand is the purest naphtha and best for cannabis extraction? Sunnyside Naphtha is what I've been able to find but want the absolute best there is in the U.S. or if I have to get the naphtha from Canada, in which case I need to know which brand. I know there's those FOAF of yours out there who has figured out the best one to use. Rick Simpson method with stainless steel rice cooker is the process I'm using. Potency tips, safety tips, and good advise more than welcome. Also what's the best process for condensing it down to be like a brick or hash coin?

Love and Peace

IF you really must use naphta, I'd go for light naphta (petrol ether), as this is easier to purge than the normal naphta.

Did you ever thought of a butane extraction?

Getting a solid block from oil isn't that easy. The consistency varies from strain to strain and also depends on variables like temperature during the extraction and/or purging process.

To get a non sticky brick you could mix the oil with drysift to make a very potent hash.
The oil becoms brick hard when you put it in the freezer.

You're going to have to do an evap test on any naphtha you buy from a hardware store or similar, regardless of what people say. The solvents available that are not marketed for use in producing goods for consumption are not regulated in a manner that safety can be assumed wholesale for a given brand.

Also have a look at hexane honey oil extraction

Use butane, hex works but is not going to leave the best product behind. Also look into a heated vacuum purge. I've been making hash oil for over a decade now, save the time and headache and just go with butane.

I've gotten very good results with heptane, and a warm water bath vac purge (3x repeated). You could even dissolve the oil in a foodsafe alcohol (pure ethanol, acetone, isopropyl) so long as they are completely dry and pure, then evep and vac purge again.

Naptha has alot of different hydrocarbons in it, and heptane is a much refined version of naptha that evaps faster, and cleaner imho. As usual, always check your msds/do an evap test.

Just purge the hell out of it, and do an alcohol redissolve and another purge. Should get all but minute traces of the heptane out, and very low concentrations of alcohols that are not toxic in the doses that would be present as impurites that did not boil off.

Works just as well as butane without the danger of butane. I refuse to pressurize a vessel that is either metal and prone to electrostatic igniton, or a plastic that could shatter from temperature stress. Too many bad stories, and a few bad personal expirences in that dept.

You can also do a iso/etoh/acetone extraction first, and then do a hot water bath on that oil extracting with heptane. Will leave all the polar bad tasting crap behind and give you very good oil/wax if done correctly.

Supercritical gas extractions are sketchy enough, let alone supercritical highly flammable gases. CO2 mabey, but only with the right equipment (unfortunately is only viable on a larger commercial scale due to the mechanics of supercritical co2 extractions. Though it did produce the best wax i've ever tasted, co2 wax that is.
