Copper Carbide
hy guys . i wanted to ask you a question , does someone have a right procedure for copper carbide synthesis ? i found something on powerlabs but i
don't understand very much . could it be made with copper sulphate instead of copper chloride ???? what are the ratio's and that stuff ??
thanks for any help .
ps. i was thinking ,i have a big copper tube that i use for blasting with calcium carbide .... do you think that some copper carbide was produced
every time before blasting the canon ????

There's a reason why acetylene bottles never have copper valves! CuC2 is extremely sensitive! You were lucky you didn't have any premature
detonations!
Aren't there any threads about silver/copper acetylide already?
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

| Quote: | The very explosive copper acetylides, e.g., Cu2C2 • H2O, can be obtained by reaction of copper(I) salts with acetylene in liquid ammonia or by
reaction of copper(II) salts with acetylene in basic solution in the presence of a reducing agent such as hydroxylamine. Copper acetylides can also
form from copper oxides and other copper salts. For this reason copper plumbing should be avoided in acetylene systems.
Silver, gold, and mercury acetylides, which can be prepared in a similar manner, are also explosive.
In sharp contrast to the highly explosive Cu2C2 • H2O, the catalyst used for the synthesis of butynediol, Cu2C2 • 2 H2O • 2 C2H2, is not as
sensitive to shock or ignition. |
Quoted from ULLMANN’S ENCYCLOPEDIA OF INDUSTRIAL CHEMISTRY 6th
Edition
In the “Handbook of Preparative Inorganic Chemistry” vol. 2, G. Brauer , Ed. (Academic Press, New York, 2nd ed.) you can find two safe methods for
synthesize pure copper carbide. But these are real lab methods.
Hope I could help.

on 1 gram silver goes 10 grams calcium carbide , then i should use a little less calcium carbide ?

you actually should download VOGELs 3rd from www.rhodium.ws/chemistry - and look in the index for copper acetylide. The preparation is described there and to call fairly easy, but you should
for heavens sake read and follow the advises given in the book - just to stay proud owner of all your fingers. This stuff is FULMINANT in the sense of
the word. It explodes when getting dry and the explosion is violent.

Wow, you must be seriously mentally retarded. I'm deliberatly trying to be overly mean, but how hard is it to run a search for
"Vogel"?

Edit: only Amazon.com outranks my pages when you search with Google for "practical organic chemistry." I'm so happy.
