In this world the words "evidence" and "significant" don't calculate and are meaningless against the word of an official tasked with the duty to imprison and humiliate you. Unless you've personally experienced a court of law in this land or witnessed and attempt to free a man or woman in it's grips you could never truly know it's horrors and abuses like I have. These people need no further incentive to deny you your rights as a human than that badge and what they perceive as their duty.. Much less being proven a liar in a court of Law. They will testify with utmost contempt to your personal freedoms and spit on their own mothers if it meant losing face in front of a colleague or respectively swear on the life of their own children if they had to lie on the behalf of themselves or their respective departments. That isn't justice it's toxic narcissism and poison psychopathy posing as societies greatest protectors and advocates. It's a shame your naive sheltered existence has corrupted your sense of compassion and duty to your fellow man and neighbor into this ugly twisted reality where you believe your captor is your friend and defender. Let's hope your never accused my friend the Law is a constrictor and your a quivering rodent locked in it's cage awaiting the serpents lunch time just as soon as they hang that despicable phrase "The People Vs" before your name.

    You don't need liquid ammonia. Just use liquid amine, like dimethylamine. Sodium produces solvated electrons not only in anhydrous ammonia, but also in amines. Dimethylamine is actually producable at home and liquid at r.t. Eschweleier-Clarke-like reactions of ammonia, formaldehyde, formic acid and possibly hexamine yield dimethylamine if conditions of reaction and proportions of reagents are controlled to prevent formation of other methylamines.

      +philip ferdroß 1. Ammonia is also flammable, highly basic and poisonous. 2. I was talking about dimethylamine, nit diethylamine. Diethylamine is harder to produce. 3. The only reason why you may want to use an amine instead of ammonia is being unable to make liquid ammonia. If he or you can get liquid ammonia, fine. But it is not the only option, in fact, if you can't get dry ice or liquid nitrogen or buy ammonia in canisters, you can use dimethylamine, liquid at room temperature, which you technically can make at home. As I said ammonia is not the only option, there are alternatives, not necesarrily better, but liquid at rt and producable using typical reagents.

    @bpark10001 5 лет назад +1

    Question about your process: normally, alkali metals attack Teflon. I assume this is because the fluorine in the Teflon "would rather" be ionically bonded to alkali metal than to carbon. Fluorine ion is in lower energy state then one covalently bonded to carbon. Direct contact by the metal results in flashes and the Teflon "scorches". (This is a common treatment when desiring to bond to Teflon.) When the alkali metal dissolves into NH3, the solvated electrons "are looking for something to reduce" (which drives your birch reaction). Why don't the solvated electrons attack the Teflon stir-bar, and rip out the fluorine, as the bare metal does? I assume if there were traces of water, the electrons would reduce the water to H2, as metal does directly?
    2nd question: How do you operate stir-bar when there is a large distance between the stir-base and the reaction flask (such as your dry-ice bath or heating mantle)? Do you have special stir-base with extra-strong magnet?

    • @tinafoster8665
      @tinafoster8665 2 года назад

      Just a guess but those Teflon molecules are actually one long polymer molecule of fluorinated carbon, and since the carbon bond to almost any atom is the most stable in the universe, that explains why the activated alkali metal atoms although they have a stronger bond strength to some atoms, are not enough to defeat the fluorocarbon Bond

    Very interesting video. Quick comment to anyone trying this at home: you can tell if you got your product by using bromine water. Olefins like 1,4-cyclohexadiene will react with the bromine, turning it clear, while neither aromatics like benzene nor alkanes like cyclohexane will react.
    There's also a characteristic bad smell to olefins, although I can't think of how to describe it. If you've ever smelled MAP gas (yellow cylinder for torches, now mostly made of propylene which is an olefin) then you'll recognize it.

    Hi NR, for the application of the Birch Reduction in the reaction to produce a certain illegal drug. Could it be that sense the alkyl chain connected to the benzene ring donates electrons to it, causing it to not undergo a reduction to produce a cyclohexyl group?

    Something doesn't make sense..
    1. Ethyl Alcohol (the kind you can drink) forms an azeotrope with water - meaning you can not (typically) get all the water out - right?
    2. Lithium is decomposed by water - right?
    3. You are using "ethanol" in your reaction shown in this video - right?
    4. Isn't the Birch reduction supposed to be done under anhydrous conditions?
    So it seems like some of your lithium would be decomposed by the water in the reaction; and, at the very least, it would make it difficult to know how much lithium (and thus solvated electrons) are in your reaction.
    What am I missing here?
    Did I mistake something that was done in the video or have my facts wrong?

    • @hantrio4327
      @hantrio4327 Год назад +1

      Your facts are wrong. Just because you can't make anhydrous ethanol via a normal destillation doesn't mean you can't make it by different means. There are many drying agents that can absorb the water making the ethanol anhydrous.

    Na/li in the pesence of liquid NH3 is birch reduction.
    Further the conditions for aromaticity are 1. Being planar
    2. Every C being Sp2 hybridised - meaning three sigma one pi.
    3. Being cyclic
    4. Huckels rule having 4n+2 pi electrons
    Aromatic compounds are extremely stable and usually show conjugation of double single double or double single LP

    It reduces the OH on pseudoephedrine to make methamphetamine. Very simple but dangerous due to pressure building up. Much safer (but more expensive and time consuming) to use HI to reduce. Oh and cleaning the Sudafed pills is literally more difficult and time consuming than making the actual drug.
