How To Make Chloroform For Survival

BIG Chloroform_1

You’ve likely watched many movies where chloroform is used to knock people out in order to kidnap them or disable them for some other reason.

It’s definitely good for that, but subversive maneuvers isn’t what it was originally made for. Originally it was used as an anesthetic to knock people out for surgery.

Sounds like a handy thing to have in your supplies, right? The problem is that you can’t just walk into your local superstore and pick up a gallon of it from the shelf beside the milk. You can, however, make your own.

Chloroform, whether pharmaceutical grade or homemade, is lethal in the wrong hands. Don’t use it without training!

That being said, if you have a medically-trained person in your group, knowing how to make it can come in handy in a variety of ways. You can use it to anesthetize people for surgical procedures,  or to operate on animals for procedures such as castration. It’s also used in pesticides, disinfectants, dry cleaning solutions, photography development and refrigerators.

So, how can you make chloroform at home? Actually, it’s not that difficult – it involves two common household items – but it is a bit dangerous for both the patient and anybody within several feet of it.

There are actually a few different ways to make it, but keep in mind that this can very well kill the patient you are trying to save. Yes, I’ve already said that, but it bears repeating. Now, on to it.

Gather Your Ingredients

You know all those warnings you’ve heard about mixing your cleaning products? Well there’s a good reason for them. When combined, certain chemicals such as bleach create toxic fumes such as chloroform (yes, I said TOXIC), hydrochloric acid, chloroacetone and other things you really don’t want to breathe.

Since we’re actually trying to make one of those chemicals, let’s proceed with it. Household bleach is your first ingredient. It needs to be at least 6 percent without any added ingredients. If you use a higher concentration, you’re going to need more ice, which I’ll explain in a second.

The second ingredient is used by most women for cosmetic purposes and by many men (and women) to shine their rides with an awesome paint job. Acetone, also known as finger nail polish remover or paint reducer. Be careful to read labels though, because these products aren’t always pure acetone, or even acetone at all. You can buy acetone in the cosmetics section of your local superstore and you can also buy it at most paint stores where it will probably be labeled simply as acetone.

The final ingredient is one that’s really tricky. You’ll actually have to walk all your way to the freezer for it. It’s ice.

So to recap, the ingredients you will need are: household bleach, acetone, ice.

Gather Your Equipment

  • You’re going to need a large glass container. HDPE buckets will work because the reagents won’t attack it, but you won’t be able to see the chloroform forming as well.
  • A separation funnel will be needed to separate the chloroform from the other ingredients. You can do it with other tools such as an eye dropper, but that’s a long row to hoe. You can get a separation funnel online for about $25.
  • A gas mask is highly recommended because of the risk of inhaling the fumes. You should make the chloroform in a well-ventilated area even if you’re using the mask. The vapors alone can make you nauseated, give you a headache or even make you pass out.
  • A stir stick will be necessary. Glass is, of course, the best tool for this job.

Make the Chloroform

I feel the need to warn you again to be careful. This isn’t something you should use as a family science experiment. If you’re ready to move ahead, gather your ingredients and equipment together in a well-ventilated area.

It’s best to start with the bleach and acetone chilled even if you’re using ice because the reaction will cause the mixture to heat up by at least 85 degrees. The higher concentrate bleach you use, the hotter it gets. The ratio for making chloroform needs to be 1 part acetone to 50 parts bleach. That’s 1 teaspoon of acetone per cup of bleach.

  • Place the bleach in the container, then add several ice cubes. Add the acetone and stir the mixture, or swirl it around if you’re using a vessel that allows you to do that without sloshing it out. If you’re using a high concentrate of bleach, i.e. 12 percent, add more ice.
  • Leave the mixture alone for 30 minutes to an hour so that the chemical reaction can develop and the mixture can cool. First you’ll notice a white cloud of vapor coming from the solution and the solution itself will become cloudy. You don’t want to breathe this! You’ll also be able to see a white residue, powder, or bubble forming on the bottom. That’s the chloroform.
  • After the hour is up and the mixture is cool, gently pour most of the liquid off the top. Be careful to leave the chloroform on the bottom.
  • Once you’ve gotten most of the liquid out, transfer the rest to your separation funnel. Let it settle, then drain the chloroform out, leaving behind the water.

You’ll yield around 50-70 percent of your starting material volume in chloroform.

At this point, the chloroform is created but if you’re going to use it on people, or animals for that matter, it needs to be distilled in order to purify it. Obviously, you’ll need a distiller for that.

Other Ingredients to Combine

If you have a copper still (and who doesn’t?) laying around, this is the way to distill your chloroform into liquid. You can use the ingredients listed above or you can use 4 parts of bleaching powder (32.5-34.5 percent), 3 parts 96% alcohol, and 13 parts water.

The actual distillation process for this is lengthy and requires several different steps. It’s not particularly viable for the average person, but I wanted to make you aware of it.

Because chloroform, either pharmaceutical grade or homemade, is thought to be carcinogenic, is dangerous to use and make, and doesn’t have much of a shelf life, it may not be your best option for use in a survival situation. Topical analgesics or oral pain meds may be the better option. Shoot, even doing it like they did in the Wild West is a better option – take a shot of liquor til you feel no pain.

Seriously, chloroform is nothing to fool around with. If you want to make it at home, now you know how but do so with care. Your life, or the life of the person you administer it to, will depend upon it.

If you have ever made chloroform or have anything to add, please feel free to do so in the comments section below.

    Thats real nice of you not to say EXACTLY how much bleach to use or EXACTLY how much acetone to use. Use several ice cubes? the last time i checked ice cubes come in different sizes. ooo ya you can use a still but we arn't going to tell you exactly how to do that either. Did you get your recipe from the worthless "anarchist cookbook"? lol Maybe next time you can give out the recipe to make nitroglycerin.

    • If you read the article it clearly states 50 parts bleach and 1 part acetone.

      • Bookworm says:

        I swear that wasnt there when I read it this morning. Sorry for my comments.I will pay more attention in the future. If you can could you explain the still part to me then?

    • howard higgins says:

      why dont u learn how to read the whole article!!!!!

  2. I recall many years ago when I was a cadet at a US military academy that one of my classmates made chloroform in the barracks which was used on an upper-classman to abduct him for a prank. After the chloroform was administered he was tied to his bed, taken to the quadrangle, and showered with ice water to await the morning formation. The guy never knew what hit him until he woke up in the quadrangle. Now days that would probably get a person expelled, but then it was just considered a funny and harmless prank. It had to be easy to make, seeing as we didn't have access to much in the way of equipment or supplies in the barracks and it was all done secretly at night after taps.

    • Many year ago one could purchase chloroform at a drug store. That is likely the source of the chloroform used in you prank.

  3. Geekytina says:

    Hi bookworm. I read this in the article. Looks like maybe it was updated. That’s 1 teaspoon of acetone per cup of bleach.

  4. A much better/easier/safer temporary surgical knock out is nitrous oxide (laughing gas). Used for dental extractions. Infuse into an oxygen feed. Easy to obtain through cake decorating suppliers or Amazon.

  5. Charles says:

    What is the "Cloudy" vapor/ stuff and the discarded liquid(water?). What nasty impurities are there that need to be distilled out? Assuming there is electricity to make ice cubes probably take them to the Hospital, unless we would be using a solar or gas generator...? Interesting skill set

  6. Bill Michael says:

    Does Theresa Crouse have a book or other publication that I could buy...???
    It would be handy to have something in one book that could explain how to make soap, antibiotics, aspirin, alcohol, vinegar, or how to find necessary things like salt in a crisis. There are so many things essential for life that our ancestors knew how to obtain that we now take for granted. Our entire way of life is based on a system that runs like a watch. Just think of how fast the grocery stores would empty out in a crisis? Fuel would disappear overnight. It's is both mind boggling and troubling to think about.

  7. Vidz Man says:

    Is There anyway I can buy chloroform instead of making it?

  8. Would be nice to see a video of this stuff being distilled. I understand its similar to distilling alcohol, but it would be nice to see this stuff to the refined end.
