19/7/2019· 1 Answer1. If you mix CaCO3 + S and heat the mix, the first thing to occur will be that sulfur melts. Second, CaCO3 loses CO2 and becomes CaO. Third, sulfur boils off (or has already boiled off). A thought that perhaps CaS + O2 would form can be eliminated on the basis that roasting metal sulfides in air produces SO2 + the metal oxide.

Preservation and Use of Calcium Carbide
Calcium carbide is readily attacked by the air and the moisture contained in the generators and consequently decomposes during the storing, with formation of acetylene gas. Aside from the loss, this decomposition is also attended with dangers. One of the oldest methods of preservation is the saturation of the carbide with petroleum.

Technology Profile: Calcium Carbide Production from …
1/3/2019· Calcium carbide is the most industrially relevant carbide because of its important role as the basis of the acetylene industry. In loions where there is a shortage of petroleum, calcium carbide is used as the starting material for the production of acetylene, which, in turn, can be used as a building block for a range of organic chemicals, such as vinyl acetate, acetaldehyde and acetic acid.
Calcium Carbide | NCpedia
Calcium carbide, a chemical compound used in the commercial manufacture of acetylene gas, was discovered accidentally during experiments in aluminum processing in Spray (now Eden) in Rockingham County. A local entrepreneur, James Turner Morehead, formed a partnership with Thomas L. Willson, a Canadian chemist, to develop an economical method for
