3. Ethylene (C 2 H 4) triggers enzymes including kinase (neutralizes acid), amylase (converts starch to sugar), hydrolase (degrades chlorophyll) and others to start ripening fruit. Calcium carbide, when in contact with moisture (such as on the surface of the fruit) produces acetylene (C 2 H 2) which is quite similar to ethylene in starting ...
The chemical formula of calcium carbide is CaC2. The chemical compound is colourless in appearance. Calcium carbide has a molecular weight of about 64.099 g/mol. It is commercially manufactured by Coke and Calcium oxide. It is a greyish-black lump or sand-like and has a garlic-like odour.
The major industrial use of CaC2 is in in the production of acetylene. Calcium carbide is prpduced in an electric arc furnace loaded with a mixture of lime and coke at approximately 2000°C: CaO + 3 C -----> CaC2 + CO. How many kilograms of calcium carbide can be prepared from 601 kg of coke that is 90.2% carbon?

Calcium carbide is manufactured in electric arc furnaces, primarily closed furnaces equipped with Soderberg electrodes. Burnt lime, coke and anthracite are used as raw materials. The raw materials must have a certain particle size (ca. 5-40 mm) to give the correct porosity in the bed and correct electrical conditions in the charge.
