What is Acetylene?
The simplest alkyne chemical
molecule, known as acetylene chemically, is C2H2.
Ethyne, Narcylen, and Vinylene are
other names for acetylene. It is frequently employed as a fuel and a component
of chemical compounds. It is handled as a solution even though it is unstable
in its pure state. The compound's two carbon atoms are joined by a double bond,
making it an unsaturated one.
A colorless gas with a faint
ether-like odor, vinylene. In water, chloroform, acetone, and benzene, it is
readily soluble. In ethanol and carbon disulfide, it is only marginally
soluble. When compared to air, it is lighter and more readily ignites. Violent
container rupture can result from prolonged exposure to heat or fire.

Chemical Properties of Acetylene (C2H2)
1. Reaction with HBr
Ethylidene bromide is the result
of the HBr treatment of acetylene.
2. Reaction with sodium metal
Acetylene and sodium combine to
form sodium hydroacetylide and hydrogen.
Na + C2H2 → NaHC2 + H2
3. Reaction with HCl
Acetylene and HCl combine to
generate CH3CHCl2.
Acetylene Uses
1. Brazing is done with acetylene.
2. utilized in the glass sector.
3. used in the production of artificial rubber.
4. utilized for soldering metals.
5. used as a food preservation ingredient.
6. used to make metal precipitate.
7. used in the production of acetic acid.
8. used as a raw material in the production of
acrylonitrile.
9. utilized while carburizing steel.
10. used as an additive in petrol.
Production of Acetylene
The incomplete combustion of CH4
has been used to create this chemical since 1950. (methane). Up till 1983,
4,00,000 tonnes were produced.
It was made in 1862 using a
reaction that Friedrich Wohlerthe had discovered. The calcium carbide reaction
is described as follows:
CaC2 + 2H2O → Ca(OH)2 + C2H2
Using an electric arc furnace, the
aforementioned reaction occurs at a very high temperature of roughly 2000 °C.
Health Hazards
When exposed to this substance,
people may experience headaches, unconsciousness, and dizziness. If there is a
larger concentration of ethyne in the air, choking death could happen.
FAQs: Frequently Asked Questions
What is acetylene used for?
In welding and cutting operations,
acetylene is used. Acetylene welding is also referred to as cutting coal or
oxyfuel. When cutting or welding materials that need temperatures of up to
3,500 ° C (6,330 ° F), this technique is utilized. Of all the gases, acetylene
can create the fiercest flame.
How acetylene is produced?
A hydrocarbon passes through an
electric arc to produce acetylene, water reacts with calcium carbide to produce
acetylene, and methane partially burns with air or oxygen to produce acetylene;
Why is Ethyne called acetylene?
From the French acétylène, the
word was created in 1864 by French scientist Marcelin-Pierre-Eugène Berthelot
(1823-1907). In 1839, German chemist Justus von Liebig named acetic acid, which
was formed from the chemical ending ene + acetyl.
What happens if you inhale
acetylene?
Acetylene inhalation symptoms
include tachycardia, tachypnea, nausea, vomiting, lethargy, and dizziness[2]. A
high acetylene exposure level will cause unconsciousness and death. A colorless
gas called acetylene is frequently utilized in welding procedures.
Is acetylene corrosive to metal?
In its purest form, acetylene is
colorless and fragrant. Although it serves a variety of purposes, acetylene is
now recognized for its ability to prevent the top-line corrosion that
frequently occurs in gas pipes. A corrosion inhibitor, it can be sprayed
because of its high volatility.
