Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Explosive: Reaction products may be explosive or sensitive to shock or friction

Acetylenic compounds with replaceable acetylenically bound hydrogen atoms must be kept out of contact with copper, silver, mercury, or alloys containing them, to avoid formation of explosive metal acetylides ("Chemical Intermediates", 1972 Catalogue, 158, Tamaqua (Pa.), Air Products and 365bet娱乐 Inc., 1972; Dangerous Substances: Guidance on Fires and Spillages (Section 1, 'Inflammable Liquids'), London, HMSO, 1972, p. 27; Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Volume 2. Oxford: Butterworth-Heinemann. pp. 5-6, 192).

Acetylene reacts with copper to form explosive acetylides (Association of British Chemical Manufacturers. 1946. Quarterly Safety Summary 17, 24).

Copper, mercury, or silver, can form explosive acetylides in contact with 3-bromopropyne (Dangerous Substances: Guidance on Fires and Spillages (Section 1, 'Inflammable Liquids'), London, HMSO, 1972, p. 27).
