Liitiumsüsinik

Liitiumsüsinik is a chemical compound with the formula Li2C2. It is an acetylide, meaning it contains the acetylide anion, C2^2-. This compound is a solid substance. It is typically a white or off-white crystalline material. Liitiumsüsinik is formed when lithium metal reacts with carbon at high temperatures, often in the absence of air. The synthesis usually involves heating lithium to its melting point and then reacting it with graphite. The reaction is exothermic.

Liitiumsüsinik is known for its reactivity. It reacts vigorously with water, producing acetylene gas (C2H2) and lithium hydroxide (LiOH). This reaction can be quite energetic and should be handled with care. Due to its reactivity with moisture, it is typically stored under an inert atmosphere or in a non-aqueous solvent. Liitiumsüsinik is a strong reducing agent. It has found some limited applications in chemical synthesis, particularly as a source of the acetylide anion for organic reactions. It is also investigated for its potential use in high-energy materials. The compound's properties make it a subject of interest in inorganic chemistry research.
