chemical properties grey or black solid with a garlic-like odour
usage used as desulfurizer and dehydrant of steel and for cutting and welding metals. in organic synthesis industry, acetylene obtanied from calcium carbide is raw material to make ethylene, chloroprene rubber, calcium cyanamide, acetic acd, acetaldehydr, ethylacetate, cyanide acetate, dicyandiamide, acetone, octanol, trichloride ethylene etc
general description grayish-black irregular lump solid. used to make acetylene and in steel manufacture.
air & water reactions reacts rapidly with water to generate the flammable gas acetylene and the base calcium hydroxide. enough heat may be generated to ignite the gas [jones, g.w. bm report invest. 3755 1944].
reactivity profile 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]. 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 once reaction starts, evolution of acetylene gas is very rapid, unpublished observations [bretherick 1995].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°c.
health hazard eye and skin irritation
fire hazard behavior in fire: if wet by water, highly flammable acetylene gas is formed.
