Epoxides are normally hydrogenated in preference to saturated ketones but double bonds are usually reduced under these conditions. It is possible in some cases to selectively cleave an epoxide without saturating double bonds by the use of the deactivated catalysts recommended for the partial reduction of acetylenes (see section IV) or by the addition of silver nitrate to the palladium-catalyzed reaction mixture. " ... 

The International Electrotechnical Commission (lEC) has placed hydrogen, acetylene, carbon disulfide, and ediyl nitrate into Group IIC. The United States, on the odier hand, has separated hydrogen and acetylene into different groups and does not classify carbon disulfide.

Pure TeNMe is said to be colorl, but becomes yellow on contact with w, due to hydrolysis to TNMe (Ref 5). Mp 14.2° (Ref 26) bp 125.7° (Ref 10) d at 25°, 1.62294g/cc RI at 25°, 1.43822 (Ref 18). The dipole moment is essentially zero, indicating the structure to be symmetric, instead of (02N)sC0N0 as had been postulated to account for its reactivity (Ref 18) CA Registry No 509-14-8 Historical It was first prepd by the action of nitric acid on TNMe (Ref 2). This reaction is the basis of large scale prepn in which acetylene is nitrated to TNMe and the latter treated with an excess of nitric acid to give TeNMe (Ref 26).

These codes are mentioned for all the substances that are subjected to regulations in Part Three. Amongst the twenty substances chosen previously only four of them have such a code. They are nitromethane and peracetic acid (code 5), acetylene (codes 5 and 6) and ethyl nitrate (code 2).

Nicodemus obtained mixtures of ethylamines on passing mixtures of NH3 and acetylene at 280-290°C over zinc chloride on pumice [232, 233] or at 350°C over a mixture of zinc nitrate, tin chloride, siUca and charcoal on diatomaceous earth (Eq. 4.56) [234]. 

Silver nitrate (or other soluble salt) reacts with acetylene in presence of ammonia to form silver acetylide, a sensitive and powerful detonator when dry. In the absence of ammonia, or when calcium acetylide is added to silver nitrate solution, explosive double salts of silver acetylide and silver nitrate are produced. Mercury(I) acetylide precipitates silver acetylide from the aqueous nitrate. 

A poorly stoppered dropping bottle of silver nitrate solution absorbed sufficient acetylene from the atmosphere in an acetylene plant laboratory to block the dropping tube. A violent detonation occurred on moving the dropping tube.

Contact of acetylene with the nitrate solution gives mercury acetylide, an explosive sensitive to heat, friction or contact with sulfuric acid. 

Nitration of acetylenes with nitryl iodide followed by elimination of HI gives nitroacetylenes, but nitroacetylenes are too thermally unstable to be useful for organic synthesis.77 Recently, nitro-trimethylsilyl-acetylenes are prepared as stable nitroacetylenes by the reaction of bis(trimethylsily)acetylene with nitronium tetrafluoroborate (Eq. 2.39).78...
