- Acetylene (IUPAC
name: ethyne) , C2H2, is a hydrocarbon belonging to the group of
alkynes.
- It is considered to
be the simplest of all alkynes as it consists of two hydrogen atoms and
two carbon atoms.
- Acetylene is an
unsaturated organic compound because its two carbon atoms are triply
bonded.
- The carbon-carbon
triple bond leaves the carbon atoms with two sp hybrid orbitals for
sigma bonding, placing all four atoms in the same straight line, with
CCH bond angles of 180°.
- The principal raw
materials for acetylene manufacture are calcium carbonate (limestone)
and coal.
- Acetylene can also
be manufactured by the partial combustion of methane with oxygen, or by
the cracking of hydrocarbons.
- Air-acetylene flames
are also used for soldering and other plumbing applications where the
very high temperature of the oxy-acetylene flame is not
required.
- Acetylene is used as
the fuel gas in atomic absorption analyzers.
- Acetylene is used in
automatic lubrication of glass bottle molds.
- Acetylene’s use in
welding and cutting applications as well as for heat treatment and
coating, makes it a very useful gas across a wide range of
industries.
- Acetylene Black is
used in the manufacture of Dry Cells - mainly to improve the
depolarizing properties of manganese dioxide.
- About 85 percent of
Chinese enterprises use acetylene, and the total annual demand for
acetylene has reached 100 million cylinders or so all over the country;
the average annual consumption for acetylene has reached 350 thousand
cylinders in big cities, 100 thousand cylinders in medium-sized cities
and 30 thousand cylinders or so in county-level cities.
- 1,4-Butanediol,
which accounts for nearly 90 percent of the acetylenic chemicals demand
for acetylene, is growing at more than 5 percent annually, fueled by
strong demand for downstream intermediates.
- With the new
catalyst, nearly all of the acetylene produced during the ethylene
manufacturing process can now be converted to ethylene, increasing
product yields.
- The acetylene yield
is the percent of the carbon in the methane feedstock that ends up in
acetylene and the hydrogen yield is the percent of the hydrogen in the
methane feedstock that ends up as elemental hydrogen.
- BASF uses large
amounts of acetylene to produce butanediol. With an annual capacity at
Geismar of 280 million pounds, BASF is the largest merchant supplier of
this product in the NAFTA region.
