Wow I am so jealous of all that calcium metal you got. Showing some reactions with it on a larger scale could make an extremly awesome video! Also congrats on 2000 Subscribers! ;-)
@@THYZOID Hm I don't have a lot of experience with calcium metal. I would try to burn it, react it with liquid oxygen, with sulfur, bromine, iron oxide and any other readily available oxidizer I can think of. Obviously in order to make an awesome video I would have to think about it a lot more and test as much as possible first.
@@THYZOID You can either use liquid N2 or treat urea with nitrous acid to make a fair amount of N2. CO2 is also released along with N2 in that reaction. If you have woulfe bottle, you can bubble the gaseous mixture through amine or alkali hydroxide solution to absorb CO2.
The reaction did not happen, you should heat it a bit longer till you actually see them react. Test tube should melt as the reaction is VERY exothermic
We still got a small amount of CaC2 though as indicated by black smoke being generated while burning the resulting acetylene. In comparison to all other videos on RUclips we mixed the reagents. The reaction may be more vigorous if the calcium just sits ant the bottom of the test tube while being molten first.
@@THYZOID just to be sure, you could repeat the experiment and bubble the gas through Ag(NH3)2OH or CuCl in ammonia. Getting precipitates shows the presence of C2H2 in the gas mixture. Just do not let the resulting acetylides dry.
@@THYZOID the melting point of calsium is 842°C ..i don't think calsium can be melted with a butane torch in a test tube.. when reaction starts the heat generated by it melts all the remaining calsium with carbon to then react with it
It can also be made with an thermit reaction. they first made it with an Mg + C2 + CaO. Thermit. Will work with Aluminium too for this reaction only a lot of heat is neccesary
It sucks that CaC2 is such a difficult to make chemical. One either has to use arc-furnaces or calcium metal. But if microwave technology becomes cheaper/simpler, CaC2 can become more accessible to people who live in places where CaC2 sales are restricted.
@@SuperAngelofglory No, he means that if it gets wet it will off-gas acetylene. There's a reasonably high risk it will cause fires/explosions if not shipped or stored properly, and gets exposed to rain or spills. So it has to be treated as a hazardous material, greatly increasing the cost (about half the cost of CaC2 purchased online is the added hazmat shipping fees) and some areas have further restrictions due to the risk.
Hey, can you tell me where you got the needle valve for the co2 cylinder from? I couldn't find any because it turns out they use an m16x1.5 thread which is unusual for gas applications. All my searches yield hydraulic valves without a seal
Hmm, that's neat making Acetylene with Calcium Carbide. BTW how is the project with Pigment with Sodium fluoride. I have researched that since I was interested in the theory but nothing came up.
I’ve actually pushed that one aside up to this moment because I’m wanting to finish other projects first. But you are right! I’ll have to get started with that one!
You can make calcium carbide easily by mixing lime with carbon and roasting it with an electric arc in a container that can vent the carbon monoxide. If you want to make phosphorus then add a bit of calcium phosphate and sand. You will get co, p vapor, SiC and CaC2. The SiC crystals also are electroluminescent like very weak LEDs glowing yellow green to blue at 5v or so.
A good try. Obviously, the temperature is not sufficient enough for the reaction to happen. I believe that this reaction requires relatively less temperature than the industrial route involving calcium oxide.
@@THYZOID Oh yes! Also, try to make it by heating the metal in the current of CO2 if feasible. It will afford a mixture of calcium oxide & calcium carbide.
This almost seems easier than trying to break up commercial CaC2 chunks to fit through ground glass joints. I bought a tub full recently as I plan to make as much CS2 as is possible having done it twice and only making a few mL each time. I want to do it in such a way that I can keep adding more calcium carbide and sulfur until I run out. I guess inside a plastic bag and hitting it with a hammer is one way to break them into smaller pieces. Nothing worse than getting a chunk properly stuck in the neck of 1000ml rbf full of more chunks although I guess you could pipette a small bit of water on it
A small handheld burner, a 0-30v 5A power supply and the lid of a can that i bent a little bit to hold a puddle of molten salt. Don’t remember what I used as electrodes. The process did generate enough heat to keep the salt molten and some kind of material was growing on the cathode, it reacted a little bit with water but not as much as pure calcium The fact that it didn’t require additional heating after starting was surprising, with the small scale
The first try to making the calcium carbide is reaction of Ca-Zn alloy with carbon (graffite). Imho, it need to more temperature, par example, from propane- oxygene furnace.
this is for a school project, btw i know if you mix calcium carbide and water causes something that i want to do at my neighbour house so its only for a school project yall
Hello dear, I am Osama from Egypt I work in an auto repair and I need calcium carbide a lot In automotive welding, soldering and soldering iron Can I make calcium carbide at home in a gas furnace with a temperature of more than 2000 degrees
@@THYZOID Thank you my dear friend for your reply But the manufacture of calcium carbide in Egypt will be a very rewarding project, God willing, and when I actually make calcium carbide, I will tell you If you would like to come to Egypt to see the project There is no one in Egypt who manufactures calcium carbide Calcium carbide found in Egypt is all import only, God willing, it will achieve huge success
A ceramic flower pot buried in sand with a piece of metal at the bottom and a carbon rod in the middle. Fill with a mixture of quicklime and carbon with a graphite rod in the center. Bridge the metal and bottom of the rod with a small amount of steel wool, then apply current from an arc welder and hold for about 20 minutes. The heat will cause the CaO to react forming CaC2 plus CO gas.
@ 1:12 Did you say that the contaminants produce "phosphine upon contact with water"?! If so, how is possible and what contaminants would be present to cause this?
If the calcium oxide source used contains phosphide it forms phosphine in contact with water. If only calcium and carbon are used as in this video no such contaminants are present.
How do I separate calcium carbide? I've been trying to figure out how to pull off a thermal decomposition method, but I keep getting all types of methods, and I don't really have that much material to experiment with each procedure I'm hearing about! Any suggestions I'd surely appreciate your time! Thank you and happy holidays.
You can try making calcium cyanamide from the carbide, then make ammonia, i.e. Frank-Caro process, the original atmospheric nitrogen fixation process before Haber process was invented.
@@THYZOID Thank you. What do you mean by purity? I want more clarification please and thank you. Charcoal of vegetable origin is not possible? thanks mr.
Already tried that using copper and acetylene from a gas bottle and it failed. But really does it work with charcoal? If it does it might be worth a try because I’ve now got better equipment.
That’s the industrial route to CaC2. It requires temperatures between 2000 and 2300*C and is commonly conducted in an arc furnace. This is nearly out of reach for me at the moment and impossible for most hobby chemists.
First! :D
How you doing 🙂
You really making a video of osmium tetra oxide 🤯

that temp sounds good. at that temperature you can even use the classical method of reacting carbon with calcium oxide

You should have tried to precipitate the acetylene as Cu2C2 or Ag2C2. Now it's bit suspicious.
I’ll redo it and upload as a short. You’ll be able to see then.
You can use lime instead of calcium metal. You will need more carbon.
How much acetylene is produced?

What is the solution did you use for mix ca and cark coal
I didn't know it's a hard to make substance. I thought it's just as simple as say, burning rock on an open fire like when making lime.
Can any kind of charcoal be used or only petroleum charcoal? What activated charcoal did you use?
any charcoal can be used but the purer the better.
@@THYZOID Thank you. What do you mean by purity? I want more clarification please and thank you. Charcoal of vegetable origin is not possible? thanks mr.
every charcoal can be used but vegetable charcoal might also contain other salts leading to impurities in the carbide and a lower yield
Can't it be substituted for calcium hydroxide in this way because of its boiling point? Calcium only?
it can be but it will require a higher temperature

@@fadiyosef4452 the purer the better.
Will calcium medicine work
African welding brought me here. Lol
Very cool man! 😁
Where to buy calcium carbide?
Thanks i needed for a Kaboom thing
Brilliant
It's not usefull, you need to mix powder way more better and heat them much longer.
Making CaC2 isn’t even useful. Just a proof of concept in todays video but I’m working on making it more efficient.
@@THYZOID I agree.
On the other hand you can use acetylene gas for making benzene by skipping it through a tube filled with heat activated charcoal.
Already tried that using copper and acetylene from a gas bottle and it failed. But really does it work with charcoal? If it does it might be worth a try because I’ve now got better equipment.
@@THYZOID
have you ever heard about
CaO + 3C = CaC2 + CO

I think it could be way more cheaper to use CaO instead of pure calcium.
That’s the industrial route to CaC2. It requires temperatures between 2000 and 2300*C and is commonly conducted in an arc furnace. This is nearly out of reach for me at the moment and impossible for most hobby chemists.
In this video calcium will stay free. gas is hydrogene, - have no black smoke after his burning, how if gas being is acethylene.
Next time use sodium and industrial grade chlorine to make table salt...
Only worth if I do a taste test afterwards
Funny, people think this makes someone cry.
Enough with CaC2, I wanna see Ca2C
Wow 😮
Oh yeah calcium is an alkaline metal
