Copper acetylide is a compound that is a hazzard in welding; it forms an explosive jell when a copper pipe is used to transport acetyline in oxyacetyline welding. The book on welding I was reading said it is shock and heat sensitive explosive. If this stuff doesn't need very specific conditions to make, constant pressure or heat applied, ti could be a very easy to make primer. In the US pennies could be used for the copper the acetyline can be captured and reused, making it very cheap to produce if it will work.
Has anyone heard about the stuff, how to producew it, det vel, sensitivity ratings, etc?

Cu2C2 is not a gel, but maybe they found it
in a gel form. The liquid that makes it gelatinous could be water or acetone.

You can't get it from reacting Cu with C2H2,
it contradicts their atomic activity levels, copper atoms never win over hydrogen atoms.

The Cu2C2 in the apparatus might form with a long time, copper always have a thin layer of
black rust on the surface, then acetylene eat through it.

4CuO + 2C2H2 -> 2Cu2C2 + 2H2O +O2

Or the acetone, being slightly acidic, cause
copper to ionize(Cuprous ion) in solution.

2Cu+ + C2H2 -> Cu2C2 + 2H+

However you can substitite pennies with copper salt solutions, blow in acetylene, see what happens=]

The acetylides can be formed from various metals, I receltly found out. Silver and heavy matals among others will do the same thing.
HMTD Factory, you must have a little more chemstry expierence than me. I'm only halfway through Chem I.

If I made you feel uncomfortable then it's my
fault, but still I got to say thanx, I start
doing pyro related stuff since grade 9, now I
am...older, still many things don't know.
