CAC2 | Article about CAC2 by The Free Dictionary

Calcium carbide interacts with water to form acetylene: CaC 2 + 2H 2 O = C 2 H 2 + Ca(OH) 2; the process is carried out in an excess of water for withdrawal of the liberated heat (30.4 kcal/mole, that is, 127.3 kilojoules per mole). Upon heating, calcium carbide interacts with nitrogen to form calcium cyana-mide: CaC 2 + N 2 = CaCN 2 + C.

Calcium Carbide - an overview | ScienceDirect Topics

Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4). Commercial calcium carbide is a gray-black material due to the presence of residual carbon.

CALCIUM CARBIDE is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862].
