I always found it a pain to get EA so I just synthesized some chloroform via the haloform reaction. It’s easy, all you need is a 3$ quart bottle of acetone and bleach(sodium hypochlorite) or pool chlorine powder (calcium hypochlorite) mix them together on ice and tadaa Ps: if you plan on trying this make sure to look at proper concentration of reactants as well as reacting small amounts on ice each time as this reaction is exotérmico and can boil the chloroform away! Wow - there's another organic chemist on the forum! I thought I was the only one. Cheers, J. Hyatt Haha, I’ve always had a passion for chemistry. When given the choice I prefer to synthesize my own chemicals... especially when they’re not easily available!

Does anyone know how to synthesize carbon tetrachloride? Best killing agent ever.

Does anyone know how to synthesize carbon tetrachloride? Best killing agent ever. , I would rather use Potassium Cyanide than Carbon Tetrachloride. Carbon Tetrachloride is a terrible carcinogen. And from what I remember (And I am absolutely positive that 242 of the members to this site will with shear delight correct me!)it does not take a lengthy exposure to do so. I used Carbon Tetrachloride in my Killing jars when I first began collecting. My father would buy me bottles at the local hardware store. I used a lot of the stuff. About the time it was connected to Cancer, I began to use Potassium Cyanide. I know that Potassium Cyanide is very deadly. Only a very small mistake and your dead and gone. When I think about all the chemicals that I have handled in my life time, I am delighted to still be alive. There was also a comment about me running for President. Someone commented in a PM that I would be worse than The Donald. Let's try this out. Should I become President, my first Executive Order. Out Law NABA. Second Executive order. All Waffle House would become National Historical Sites. And my Third Executive Order. All elected politicians caught stealing tax payer money. Death Penalty. The official White House Publication: Mad Magazine. I would also consider a weekly Enema for all Elected Politicians. They are so full of it anyhow!!! Any other suggestions?

'58 Chevy,
I wouldn't recommend making your own carbon tet, unless you're skilled in gas handling and have a good fume hood available. (And it might be easier to get carbon tet than a cylinder of chlorine - both are strictly regulated for shipping and very expensive to ship/receive). Besides,chronic CCl4 inhalation can eventually cause chemically-induced hepatitis. I go with ethyl acetate myself (except I use ethanol or isopropanol for injections - Et acetate works, but it degrades plastic syringes pretty quickly - the plastic swells and jams the plunger. Low alcohols don't do this.)
When I was a kid starting to collect, I could buy bottles of CCl4 (spot remover) at the grocery store. Could order exotic bugs easily, too - and O. alexandrae males cost about $75 from A. Glanz. Them were the days!
Cheers, jh

Thank you John Hyatt. I could not remember the name (Commercial) for Carbon Tetrachloride. Spot Remover.
My father also bought Carbon Tetrachloride at the Rexall Drug Store. It came in brown colored bottles. That was over 65 years ago.

John, you had spare $75 as a kid? That was a splendid childhood . (Around $650 in today's worth)

Well, I said they cost $75 -- didn't say I bought one. But, oh how I loved reading through his catalogs! It was a really good summer week back then if my lawn mowing enterprise brought in more than $5. My alexandrae was $175 by the time I got it (and a job)in the early '70's.
Cheers, jh

They are typically a cloudy and not quite clear plastic so I guess you’d be better to stick with alcohols.

Is there any other chemicals that you guys use to dispatch specimens? Anyone tried H2S?

Speaking of syringes, In have used an ancient glass hypodermic needle since I was still wet behind my ears. I have two complete syringes and 25 new points I found on line 20+ years ago.I also have plastic needles as my wife is diabetic. I have had the glass syringe during my hgh school days.

I also used lots of Carbon Tet when I was a kid. It killed bugs instantly. I was very disappointed when it went off the market. However, 50 years later I was diagnosed with cancer. I don't know whether the CCl4 had anything to do with it, but it very well could have. I have also used benzene-based chemicals to deter dermestids. After my diagnosis, I no longer use any of that stuff. Ethyl acetate is now my killing agent. It works very slowly in comparison to carbon tet, but it's supposed to be much safer. Luckily, I'm now in remission and hope to stay that way.
P.S. I like your executive orders, Leroy. You've got my vote.
