Reaction on contact with moisture forms explosive acetylene gas. Flammable on contact with moisture, acid or acid fumes; evolves heat or flammable vapors. Moderate explosion hazard. Incandescent reaction with Cl2 (245°C), Br2 (350°C), I2 (305°C), HCl gas + heat, PbF2, Mg + heat. Incompatible with Se, (KOH + Cl2), AgNO3, Na2O2, SnCl2, S, water. Mixtures with iron(III) chloride, iron(III) oxide, tin(II) chloride are easily ignited and burn fiercely. Vigorous reaction with methanol after an induction period. Addition to silver nitrate solutions precipitates the dangerously explosive silver acetylide. Copper salt solutions behave similarly. See also CALCIUM HYDROXIDE and ACETYLENE.

Specification

?Calcium carbide (CAS NO.75-20-7) is also named as AI3-03101 ; Acetylenogen ; Calcium acetylide (Ca(C2)) ; Calcium carbide (CaC2) ; Calcium dicarbide ; Carbure de calcium ; Carbure de calcium [French] ; Carburo calcico ; Carburo calcico [Spanish] ; Ethyne, calcium deriv. ; HSDB 1434?.?Calcium carbide (CAS NO.75-20-7) is grey or black solid with a garlic-like odour. It can reacts rapidly with water to generate the flammable gas acetylene and the base calcium hydroxide. Enough heat may be generated to ignite the gas. 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. The carbide burns incandescently when mixed and heated with lead difluoride, magnesium, hydrogen chloride, and tin (II) chloride,?respectively. Interaction of Calcium carbide with methanol to give calcium methoxide is vigorous , but subject to an induction period of variable length. Once reaction starts, evolution of acetylene gas is very rapid, unpublished observations. Mixing Calcium carbide with silver nitrate solutions forms silver acetylide, a highly sensitive explosive. Copper salt solutions would behave similarly. The mixture of Calcium carbide and sodium peroxide is explosive, as is Calcium carbide and perchloryl fluoride as gases at 100-300 °C.? Eye and skin will?irritate by?Calcium carbide .?If wet by water, highly flammable acetylene gas is formed.?

10.3 Possibility of hazardous reactions

Not combustible but forms flammable gas on contact with water or damp air. Many reactions may cause fire or explosion.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\u00b0C., respectively, [Mellor, 1946, Vol. 5, 862]. The carbide burns incandescently when mixed and heated with lead difluoride, magnesium, hydrogen chloride, and tin (II) chloride, [Mellor, 1946, 1940, 1946, and 1941], respectively. Interaction of calcium carbide with methanol to give calcium methoxide is vigorous , but subject to an induction period of variable length. Once reaction starts, evolution of acetylene gas is very rapid, unpublished observations [Bretherick 1995]. Mixing calcium carbide with silver nitrate solutions forms silver acetylide, a highly sensitive explosive. Copper salt solutions would behave similarly, [Photogr. Sci. Eng., 1966, 10, 334]. The mixture of calcium carbide and sodium peroxide is explosive, as is calcium carbide and perchloryl fluoride as gases at 100-300\u00b0C.
