How you store it until you can deal with it, what you do to neutralize particularly nasty stuff, recovering anything that might be worth the effort. And while this was definitely cool and informative, it would be showing off a very practical use for your skills and knowledge to take the scary uh-oh stuff and change it back to (relatively) harmless and/or useful material.

On the other hand, the first commercially used, synthetic antipyretic/analgesic without an antiinflammatory effects oxidized people's hemoglobine (Fe2+ -> Fe3+) and hence was quite toxic aswell, besides being an absolute meanie to liver cells (it had a freaking hydrazine group!), so there's that.

      @@j0rmis I think the TS meant Antipyrin (Phenazone). The N-N part in its pyrazolone ring indeed comes from phenylhydrazine precursor and resembles a substituted hydrazine, but, strictly speaking, isn't one. Due to the amide group in the ring it is not even nearly as toxic as many other hydrazine derivates. Although even some purely hydrazine-based molecules are still used as efficient drugs today, so not all hydrazines are that evil. )))

      Saying that it has a "hydrazine group" is either disingenuous or from a lack of understanding (likely the latter). There is nothing in the literature that I can find that even suggests that phenazone is metabolized to hydrazine in the body, so then we're just down to kind of "this compound has a chlorine atom, so it must be as bad as chlorine gas, a chemical weapon used in WW1" etc. (using an extreme case to exemplify here). Though I'm happy to be shown evidence of the contrary.

    I was pleasantly surprised to see that bromoethane was a reagent in this reaction. As it was a critical component in the TEL additive package.
    The fuel additive was called Ethyl Fluid and it was a mixture of Tetraethyllead, Ethyl Chloride, and Ethyl Bromide. (Old names for chloroethane and bromoethane) the haloalkanes were used as the lead scavengers. Without them, lead oxide formed during combustion of TEL would build up inside the engine as a solid residue.
    The lead scavengers were used to create lead chloride and lead bromide. These compounds, exposed to the temperatures of the combustion, would form vapors as opposed to dust. And these vapors were much more easily exhausted from the engine.
    TEL got the lead into the engine, ethyl chloride and Ethyl Bromide for the lead out of the engine (and into the air we breathed) And that's Ethyl Fluid for ya!

    I had a two stroke scooter. A moped. A 1976 Puch Maxi. I was building it all back to showroom perfect for my daughter to ride to college classes and back. I lowered the gear ratio by putting smaller sprocket up front and larger sprocket in back. I got it a kit to increase engine displacement from 49cc to 70cc. When done, I noticed that the kit had engine knock that was severe at higher revs. I took it to the local scooter mechanic that sold the kit. He said He didn't notice any "Pre-ignition". He didn't understand the difference between pre-ignition and detonation. I recognized the problem as being too high of a compression ratio for the available pump gas octane ratings. I could not find TEL. I made a thick copper head gasket. He argued against it, insisted there's nothing wrong with my scooter. I was old enough to be his grampa, I remember what these things do when running right. I know. He doesn't. So I put the shim for the head in. It lowered the compression enough for 93 octane fuel to no longer detonate. I made him ride my scooter again. He came back shocked, giggling, excited. In complete disbelief. Now I get VP racing fuel and I took the shim out and I mix Klotz oil in. My sprocket gearing was to lower top speed from 43MPH down to under 30MPH because the stock brakes can't handle the speed. The whole scooter wasn't MADE for speed. I could at least make it accelerate really good, though! My daughter then raced it. She won every race until the owner of that scooter shop had to figure out how to do his job. Higher octane is what you get from TEL. Higher octane is required by higher compression combustion chambers to slow down the rate at which the fuel-air mix burns. That's what exhaust gas recirculation (EGR) does in emissions - equipped cars. Too low of an octane allows the fuel-air mix to actually explode, instead of slowly burning, expanding and pushing the piston down.

      Nothing else comes close to TEL as far as an octane booster. As far as testing just take your samples to Inspectorate or any other fuel testing lab and have them run it in a CFR engine. Adding more TEL to gasoline has diminishing returns. 16:1 static compression isn’t a real test as the dynamic compression will vary depending on cam timing as well as engine speed. I’ve run 15:1 static compression engines on 110 R+M/2 gasoline without any detonation and I’ve had 12:1 static engines that couldn’t run on 110 without retarded timing. These engines had nearly identical combustion chamber designs but vastly different valve timing events.

    I wonder what commercial process was used to make tetraethyl lead when this was an octane boosting additive added to gasoline. This process may be fine for making small quantities of tetraethyl lead in a laboratory, but many years ago large quantities of tetraethyl lead was made. I am glad that gasoline is now unleaded, because tetraethyl lead is very toxic.

On top of that, how do you safely dispose of it? Because it's not like it can be burned, as it releases lead oxide fumes, and it definitely can't be poured off anywhere.

      If you want to add tetraethyl lead to gasoline, dichloroethane must be added. Otherwise lead oxide is deposited in the engine. About 0.7 g TEL per liter is enough. In addition, 0.7 g dichloroethane per liter. However, leaded petrol must not be used in cars with catalytic converters!

    • @Toca_waffle843
      @Toca_waffle843 Рік тому +1

      Not advisable anywhere that they monitor car emissions, the lead will poison your catalytic converter. The introduction of catalytic converters to reduced photo-chemical smogs was the main driver of the downfall of leaded fuel (not the reduction of lead in the environment as many think)

    You forgot to mention that it also lubricated the valves, the early engines made to run on leaded fuel had soft valves and seats and when leaded fuel was stopped all those engines had to have hardened valves and seats fitted

    • @nerd1000ify
      @nerd1000ify Рік тому +1

      That aspect is somewhat overstated, and depends a lot on engine design. Diesels have never used leaded fuel (would be very counter-productive for them) and many got away with soft valve seats anyway. Some gasoline engines from the leaded era are ok with unleaded fuel, others suffer valve seat recession rapidly under the same circumstances. Probably related to average exhaust temperatures.

      @@nerd1000ify yeah some petrol engine originally designed for leaded petrol could last a decent amount of time on unleaded if they weren't under a lot of stress but mostly it was later models with better valve material that handled it better or they were really old low compression, low speed engines.. all old petrol engines did suffer to some degree from the removal of the lead, it's just a matter of some fairing better than others.. diesels run on lite oil so there's some lubrication there anyway and old diesels didn't produce a lot of power for their size, many modern diesels do run hardened valves and seats because of the higher rpm, egt and often being turboed.. heat isn't the only thing causing valves to wear, it also depends on the springs fitted because valves spin as they open and close, plus heavier springs also slam the valves closed harder, there's many factors that come into how much a valve will wear.. I've got some engines originally built for leaded fuel bury the valves so deep that they no longer seal because they won't even close anymore so i had to modify them and i've got engines that are still running on the old soft valves but I know they have suffered extra wear because of the lack of lead because I've checked them and relapped them when lack of compression became a problem earlier than it would have on leaded fuel

      @Mark Short do you use lead replacement additives? They're still often sold in Australia for older cars, but I don't really have any reference for how well they work. Most are potassium based as I understand it.
      To my knowledge the highest performance engines always used hardened seats even with leaded fuel. As you pointed out, the stress on the motor plays a big part.
      Leaded fuel is itself harmful to the valves, during WW2 the Germans found that lead (or maybe the HBr made by burning lead scavengers added with it) eats low alloy exhaust valves (due to nickel and cobalt shortages they weren't using conventional stainless) even though the hardened seats were OK.
