well lately i`ve been reading the improvised primary explosives and i found a recipe to make copper acylide by making some copper hydroxide (by mixing copper sulfat and sodium hydroxide both dissolved in water and then filtering the WHITE copper hydro...)and then bubleing acetylene gas triugh the copper hydroxide solution .....
but when i tried to make it it didnt work coz 1st when i mixed the 2 solutions the resulting solid was blue not white and while i was filtering it it turned dark brown or black .and when i tried to dissolve it in water to buble the C2H2 it didnt dissolve .
so plz guys does any one have another recipe for copper acetylide ?

Take a jar and place in 25 grams powdered copper and 12grams CuCl2. Pour 50-60 cm3 conc. hydrochloric acid. Heat this until it starts to boil and the green colour of the solution should disappear. Wait until it cools to room temperature and pour it into distiled water(it is said "pour it into a glass of distiled water') and white precipitate of CuCl should form. Mix this with 25% ammonia solution(NH3) until the precipitate dissolves.
CuCl+2NH3=[Cu(NH3)2Cl]
Bubble acetylene through this solution to get red-brown precipitate of Cu2C2.2H2O which is the cuprum acetylide.
This is from "Demonstrations of Inorganic Chemistry" which is university maual and not some crap book, I've never tried this, but I hope it works! also not sure about the last reaction, it could be something like
2[Cu(NH3)2Cl]+C2H2=Cu2C2+2NH4Cl+2NH3???

Right but you forgot to tell:
-the green color of CuCl2 truns into a dark brown color when heated with HCl and Cu.
-The white CuCl precipitate can't be kept long so use it fast by filtering it and then dissolving it in NH3 solution (the solution turns blue).
-after bubbling the C2H2 through the blue solution filter it fast and wash it with distillated water, then aceton, then ether and let dry (because water gives the parasit reaction Cu2C2-->CuC2 + Cu- no difference in color but the later is no more explosive!!!I have had that bad experiment and even heating it when dry afterwards on a flamme only gave a little spark)!! Very sensitive explosive stuff so don't store too much in one place nor manipulate!!!
