excuse me. What kind of metal wire is made of keten lamp?

@@user-tn4iy6sy8xnickel-chrome alloy, commonly called nichrome wire

Haha, experimental guys like me rely on you, perfect symbiosis😆.

+haugstule I do! I just created it 2 days ago. www.patreon.com/DougsLab

Hey while you're at it, make some her0in too. I was looking for Heinz brand acetic anhydride down at the Grocery Goblin last month but they didn't have any in stock BECAUSE I MADE IT UP. Hell, there isn't even a store called Grocery Goblin, I just wanted you to think that I was cool.😢

just a quick ? do you know what else can be made with acetic anhydride?

+Lucas Maugeri Thanks for your concern! I should have pointed that out in the video in case someone tries to copy this. I have been running the ketene generator carefully for over a week now, and I should be releasing the video about acetic anhydride in a few days. I will definitely be highlighting the toxicity in that video. Otherwise, everything is fine over here. :) And yes, I did some extensive studying.

+Doug's Lab Great! Competent - and this includes safety first and foremost - and enthusiatic chemists, with a real passion for what they do and who are willing to share their hardly acquired knowledge are a rare gem nowadays. Keep inspiring the world, bro!

Nichrome

I'd say it won't. Maybe in a 25 meter radius you can assure yourself a survival but 5 meters won't make a guarantee. I think the vapors don't get reacted all the way. I think it reacts with the surface of the vapors. Then the next layer/surface untill it's gone. Since it's so toxic, I would assume it's not wise to bet on water reactions. Better to have a proper gas mask or something like that. Honestly, I think phosphorus pentachloride is even safer for this experiment, even taking into consideration the leftover phosphorus trichloride.

@@tracnemaker123 There are lotteries where you might win a million dollars. This seems like a gamble with no good prize.

Ketene gas may be the chemical agent that was responsible for the 68 people who died of EVALI, and the others who ended up with permanent lung damage. It's not known if it was one chemical or more than one, but ketene is a strong candidate. Vitamin-E accetate is converted to ketene at temperatures seen in vape pens. THC-acetates also end up as ketenes, when temps get high enough. Lung injury aint pretty.

I think so. Also using mek instead of acetone into GAA gives propionic/acetic anhydride

@@ryans3442 can u explain how

Replace the propanone (acetone) with 2-butanone (mek)

+Chemistry Yes, but the air will be purged first! If not, there is likely to be an explosion.

+Doug's Lab Ah - well I'm looking forward to part 2. Did organic chemistry start catching your interest? As far as I can recall you've done a lot more of it recently.

+Chemistry Yes, I am mainly interested in organic chem. Most of the inorganic stuff you'll see me do is preparation of catalysts, oxidizing agents, etc. for organic reactions.

You can purge the air put with wippets or some other inert gas

nope you need air for that oxydation

Temperature and nonreactivity I'd imagine. I bet tungsten would work but I'll let the experts chime in. Tungsten is a pain in the ass to do a lot of things with because of its ridiculously melting point.

You really need to use a variac so you can dial in the temperature with precision. I could be wrong, but I think the flash point of the acetone vapor is just barely above the temperature where it transforms into ketene, assuming you haven't flushed the oxygen out of the lamp beforehand through maybe flooding it with a heavy gas like nitrogen before first running it. But yeah, get yourself a variac and a handheld infrared thermometer with a laser sight because 1) you'll need both, and 2) honestly, you deserve them. Spoil yourself!

+KZfaqcomenter365 I have never had problems with it.

Where did you get that glass bulb? Is it just a bulb for Kugelrohr destillations?

bdbdbd It is a solvent reservoir for chromatography

Any new content coming up on your channel bdbdbd?

Is this really that dangerous of a synthesis?

@@bartacomuskidd775 well, yes. But thats not why he would get in trouble. He would get in trouble because this is the main precursor for converting morphine to heroin. Google how much of this is confiscated every year... Tons and tons.

Florida doesn't have many poppy feilds as far as the eye can see so I think it's a moot point

@@ryans3442 There definitely are poppy fields in Fl, and he also doesn't live in Florida. he lives in the mid west I believe. But people have been busted for having large poppy fields in the United States before. No reason to think that there aren't any currently just because they haven't been caught.
