Acetylene (IUPAC name: ethyne) is a simple alkyne chemical compound with the formula C2H2. It is an extremely flammable and unstable hydrocarbon used as a fuel, welding gas and chemical feedstock. It is typically kept in a solution, due to its instability and volatility.
Acetylene’s most common uses are as welding gas and as a chemical feedstock for polyethylene plastics and acrylics. Acetylene (acetyline [sic]) is typically used with oxygen for oxy acetylene cylinders welding, cutting, brazing, flame hardening and more.
Acetylene is highly flammable and has a very broad range of flammability – from a lower flammable limit (LFL) of 2.5% to an upper flammable limit (UFL) of 81%. Oxy acetylene cylinders is also the hottest burning fuel.
Acetylene is a colourless gas with a garlic odour.
Acetyline is a common incorrect spelling.
Acetylene Cylinder – Acetylene Cylinder Sizes – Acetylene Bottle Sizes
Acetylene welding gas is supplied in an acetylene cylinder sizes that include E and G acetylene cylinder sizes. Highly reactive, acetylene is dissolved in acetone and contained within a porous mass inside of a steel oxy acetylene cylinders (acetyline [sic]).
The monolithic mass of porous materials, inside the oxy acetylene cylinders, can include things like firebrick, balsa wood, charcoal, or shredded asbestos. More typical is a monolithic block consisting of calcium silicate hydrate.
Acetone helps stabilize the acetylene gas by making it non-reactive. A low auto-ignition temperature of acetylene means that minimal energy is required to ignite acetylene in air or oxygen.
It is also reactive with copper tubing and brass fittings, so they should not be used.
Stainless steel tubing is the preferred material.

Oxy Acetylene Temperature – Oxy Acetylene Flame Temperature
Acetylene when burned with oxygen has an oxy acetylene temperature of 3,330°C or 6,020°F, hottest of the regular gaseous fuels.
Pure acetylene is intrinsically unstable so it is typically stored as dissolved acetylene (acetyline [sic]) in a solution of acetone. Dissolved acetylene is stored in special oxy acetylene bottles filled with a porous material that prevents the gaseous acetylene from collecting in voids within the oxy acetylene bottles.

Propane vs Acetylene: Acetylene & Propane Torch Flame Temperature
When comparing propane vs acetylene, propane cannot be used for gas welding. Propane can be used for brazing, but acetylene (acetyline [sic]) is better when it comes to thick flow brazing. The oxy propane torch flame temperature is 2800°C. The oxy acetylene flame temperature is 3330°C.
Both propane and oxy acetylene bottles can both be used for cutting but propane requires a different cutting technique.
Both propane and oxy acetylene bottles can be used for heating. However, propane will give off more total heat even though oxy acetylene flame temperature is hotter.
When both are used with oxygen, propane requires about 4x more oxygen than does oxy acetylene flame temperature.
Who Discovered Acetylene?
The following is a brief timeline of the history of acetylene (acetyline [sic]) :
1836 – Acetylene (C2H2) was discovered by English chemist Edmund Davy. He discovered it accidentally whist experimenting with potassium. He produced potassium carbide – K2C2 – which reacted with water to release acetylene. He thought it would be used as an illuminating gas.
1860 – Acetylene was rediscovered by Marcellin Berthelot, French chemist. He named it “acétylène”. He also discovered a number of different ways to produce acetylene.
1950s – Acetylene manufactured by the partial combustion of methane (natural gas) or as a by-product in the ethylene stream from hydrocarbon cracking.
What is Acetylene Used For?
Here are some of the most notable uses for oxy acetylene bottles:
- As an industrial gas – oxy acetylene bottles for gas welding and cutting
- Oxy acetylene bottles used for lighting purposes before safer forms of lighting were available
- As a chemical feedstock for polyethylene plastics and acrylics
How is Acetylene Produced and Stored in Oxy Acetylene Bottles?
- Acetylene (acetyline [sic]) is manufactured by the partial combustion of methane (natural gas) or as a by-product in the ethylene stream from hydrocarbon cracking.
- Pure acetylene can easily explode when in liquid form, solid form or while being pressurized.
- To make it more stable, acetylene is supplied and stored dissolved in acetone or dimethylformamide (DMF) in oxy acetylene bottles.
- This acetylene mixture is placed into oxy acetylene bottles containing a porous filling of agamassan.
- This oxy acetylene bottles makes acetylene safe to transport and use, given proper handling.
- Acetylene (acetyline [sic]) is the simplest alkyne hydrocarbon and stored in oxy acetylene bottles
- Acetylene is colourless and odourless (in pure form)
- Acetylene can have a noticeable garlic-like smell if it contains impurities, such as hints of arsine and phosphine.

Oxy Acetylene Flame Temperature
An acetylene/oxygen flame burns at about 3,500°C (6,332°F or 3,773°K). In comparison, an LPG-propane/oxygen flame burns at about 2,253°C (4,087 °F or 2,526 °K). An ordinary LPG-propane/air flame burns at about 1967ºC (3573ºF or 2,250°K).

Oxygen gas cylinder sizes (welding gas bottle sizes) have compressed oxygen gas, which is typically supplied with a purity of 99.5% or higher.
Oxygen gas is colourless and odourless.
Oxygen gas is a non flammable – oxidising agent.
It supports combustion and may cause fire/explosion in contact with incompatible substances, strong acids, reducing agents, combustibles and flammables.
Materials which burn in air, will burn more vigorously in oxygen enriched atmospheres.
Oxygen Gas – Common applications include:
Used with a fuel gas for cutting, welding, brazing and soldering.
The use of oxygen gives higher oxy acetylene bottles flame temperature than if air is used.
In plasma and laser cutting steel, an arc or a laser beam is used to heat the steel to its ignition temperature.
Oxygen is then used in the same way as with oxygen cutting to create an exothermic reaction and to blow away any metal oxide or slag.
Thermal lancing oxygen is used in conjunction with the steel lance to create a high oxy acetylene bottles flame temperature melting process capable of drilling or cutting through materials such as concrete, brick, stone and most metals.
Used as an assist gas in lasers for cutting mild steel.
