Chemical Properties
white powder(s); unstable; prepared by reacting acetylene with silver salts ammoniacal solution; used as a detonator [HAW93] [KIR83]
Physical properties
White powder; unstable; explodes when subjected to heat or shock.
Uses
Its limited use is only as a detonator. Riskof its formation may arise when silver metalor its salt solution comes in contact withacetylene.
Preparation
Silver acetylide is prepared by passing acetylene through a silver salt solution.
Fire Hazard
It is extremely sensitive to shock when fully
dried and can explode at a slight touch. It
is, however, stable under moist conditions.
It is somewhat more sensitive than cuprous
acetylide. It explodes violently when heated
to 120°C (248°F). Reactions with dilute acids
produce acetylene, which is flammable and
explosive in air. It reacts with silver nitrate,
forming a complex C2Ag2·AgNO3, which
can explode when dry by heat or spark.
