2017-11-17· Acetylene can be produced three different ways: It can be produced by the reaction of water and calcium carbide, by partial combustion of oxygen and methane, and by passing hydrocarbon through an electric arc. To get a better understanding on how acetylene gas works, we'll take a look at some of the most common uses of acetylene and how they are applied in various industries.
Failing to find anyone willing to buy their calcium carbide and acetylene patents, Morehead and Willson turned their attention to finding and promoting uses for the products themselves, beginning with acetylene in lighting. After they showed that acetylene could produce a flame 10 to 12 times brighter than that of coal gas, its use as an illuminant developed rapidly. Willson made the first ...

Product Features of Calcium Carbide. 1. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas .
Calcium carbide cac 3 is a chemical compound used industrially in the production of acetylene and cyanamide 1. carbide waste is a byproduct from the use of calcium carbide to generate acetylene gas. the acetylene gas in combination with oxygen produces oxyacetylene flame used by panel beaters and welders for welding and fabrication work.
By Damien Thryn Calcium carbide is a chemical compound with numerous industrial applications. When combined with water, it produces acetylene gas, which is used in welding and cutting torches. According to the Hong Kong Trade Development Council, calcium carbide also constitutes a key component of most polyvinyl chloride (PVC) produced in China.
2018-08-16· Calcium carbide was used in a Cu I ‐catalysed three‐component coupling with ω‐chlorinated ketones and primary amines to generate terminal 2‐alkynyl‐N‐heterocycles. The formation of an imine and the subsequent intramolecular substitution results in an active electrophilic iminium species, which can be alkynylated by in situ formed copper acetylide.
An acetylene gas miner's lamp Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C 2 H 2) which is created by the reaction of calcium carbide (CaC 2) with water (H 2 O). Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles.
Failing to find anyone willing to buy their calcium carbide and acetylene patents, Morehead and Willson turned their attention to finding and promoting uses for the products themselves, beginning with acetylene in lighting.

1. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire.
When calcium carbide comes in contact with the water, carbon from carbide mixes with one atom of hydrogen from the water and produces acetylene gas: CaC 2 + H 2 O = CaO + C 2 H 2. The principal impurity in commercial calcium carbide is CaO which reacts with water according to the reaction: CaO + H 2 O= Ca(OH) 2 +15.1 kcal/g-mole. Acetylene gas is unstable when compressed to high pressures, .
