Hazard Predictions

• Explosive: Reaction products may be explosive or sensitive to shock or friction
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Metal acetylides are formed when metal amides such as sodium amide (NaNH2) are mixed with acetylene (P盲ssler, P. et al. 2011. Acetylene. Ullmann's Encyclopedia of Industrial Chemistry. (Online)). Other strongly basic compounds may react similarly. Many metal acetylides are explosive, especially those containing heavy metals such as copper, mercury, silver, or gold. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.
