Any of you worked with hexane before?

Any of you worked with hexane before? I want to extract aromatic oils from local grasses and flowers and imitation crab, I read that hexane is used for that. Apparently I stick that stuff in a pan, pour some hexane on top, throw out the grasses when they're spent, add new ones, rinse and repeat, boil off hexane at 60 Celsius. Is it as easy as it sounds?

      No I want to extract crab essence from imitation. Also grassy smells to use in diy perfume.

      That shit is poisonous. Just make/buy an expeller.
      Obviously solvent extraction is more efficient (what you’re recommending) but it’s not exactly for the local newbie making tee aitch cee

      I'm not gonna ingest the product. I figured if I take the jar outside and boil out hexane there and dilute what remains with carrier it's not gonna be harmful.

        If you insist on using solvents, which hexane is an INDUSTRIAL standard for, here’s some light reading https://en.wikipedia.org/wiki/Liquid%E2%80%93liquid_extraction#Techniques

        How are you going to purge the residual hexane? I have worked with it before.

      Butane extraction is simple enough that even a complete retard could do it.

    Don't even bother asking for help with perfumery, people react weird to it. It's beyond their comprehension despite being practiced for thousands of years. Even chemists aren't interested in hearing about it.

      I mean, what kind of man is actually spending his time and effort trying to make essential oils and perfumes?
      Its pretty fucking pathetic.

    It is a simple procedure but you'll need to separate and discard the aqueous layer from the oil layer before you boil off the hexane. If you have no chemistry knowledge you will need to find out which one is which.

    I dont know what you're trying to do, but you can buy hexane as CRC Electronic Cleaner. It used to be mostly hexane anyway

    Be careful with hexane. It has a very low lower explosive limit , which means the vapor concentration required for a ignition to occur is low. 1.1%

    What a lot of people do is extract a "concrete" using hexane and then evaporate off most of it (rotary evaporator is best) and then add high purity ethanol and heat that past the boiling point of the hexane.

    This will remove most of the hexane and ethanol has a sweeter, nicer smell than hexane does.

      First thing is to just consider buying VM&P naptha from the hardware store. It's cheaper and more accessible than hexane in small quantities. It will probably be 15-20$ per gallon at your local hardware store. This naptha is a mix of hydrocarbons consisting mostly of hexanes and heptanes.

      If you want a "purity test" for your naptha before use, then splash some of it on a piece of clean glass and let it evaporate. No residue = no substantial non-volatile impurities. The entire concept with varnish makers and painters naptha (VM&P) is that it's a 100% volatile light petroleum solvent.

      What you really want to watch out for with this shit is that it's an extremely flammable liquid which puts off very flammable fumes. The vapors can travel from a pan full of the liquid material in order to go across the room to a source of ignition such as a water heater or refrigerator contactor. It shouldn't be used in an area where there are sources of ignition present. You asked about boiling it off---- most people don't have a safe way to do that at home (NO, a rice steamer is not a safe way to do it)

      I can not emphasize enough how flammable and hazardous this material for careless users.

      You can simply soak your imitation crabmeat in the naptha for hours/days, possibly agitating the mixture occasionally, then strain off the liquid and set it in a pan to evaporate outdoors. The imitation crab residue/oil/extract will be left in the bottom of the pan to be scraped up or else taken up into alcohol or another more friendly solvent such as glycerine or coconut oil.

      Another thing to consider is that if you're using indica or sativa crabmeat, then long soaking periods will draw more and more undesirable chlorophylls and waxes from the crabmeat--- in other words, a short soak/shaking followed rapidly by straining and evaporation will give the best golden crab oil. If the contact time is too long then you will wind up with a dark colored and sticky/greasy oil

      Thanks. I was gonna evaporate it on the balcony 6 feet away from the boiler. Doubt it would have boomed but not gonna risk it.

      Re boiling it off, I was going to boil water in a pan, move it somewhere safe, and place the container with the hexane in the pan so it heats up without being exposed to flame. Since it has a low evaporation point. Gonna go with something safer.

    Short answer is: yes
    Longer answer : if you have to ask here, you are going to fuck up, cause an explosion and poison yourself.

    I used heptane once for an extraction. I'm no chemist, and I won't pretend to know what's safe, but I evaporated it in the backyard in a pie plate on top of a slow cooker steaming water and it seemed to work as intended. Nothing caught fire when I tested my extraction, but there were probably a few weeks for it to air out. Would have used naphtha, but it's not legal in utah.

    No hexanes are ultra volatile and will explode when heated. You can extract aromatic oils by heating them in neutral cooking oils on a double boiler, no need for something as heavy duty as hexane. If you wanted to extract stuff to use as a reagent hexanes would make sense but for aromatic oils it's overkill and could start a fire.

      No, it will not immediately explode when it's exposed to any heat. It doesn't seem like you actually know what you're talking about.

        Got a gas stove at home? Light a cigarette? Unplugging a magnetic stirrer? Hexane vapors will explode because you forgot to turn on the fan. Seems like (you) haven't worked with hexanes because they're infamous in home labs and research settings for blowing up in unventilated spaces. They're also an irritant/carcinogen and even with a long period of drying in a hood you're gonna have a fraction of them left in your sample, this is why hexanes are not used in cosmetics.

          I've worked with large amounts of hexane and methanol in a chromatography system. You have to have a sufficient buildup of fumes in the air to actually ignite, just applying heat to it or having it near an outlet does not mean it's going to immediately explode.

    how will you boil it off without thermostat? that shit is HIGHLY flammable, you can just heat it up conventionally
