This blog is the fourth in a series of blogs I plan to write
providing use, price, and production data on high-use inorganic and organic
chemicals. Click here to see the first
blog in this series and a list of chemicals to be featured. This blog provides data on benzene.
Uses. Uses of benzene
include:
Ø
As a starting material in synthesizing other
chemicals;
Ø
As a gasoline additive; and
Ø
As a solvent.
Benzene primary use (more than 90% of benzene used) is as a starting
material in synthesizing four chemicals:
ethylbenzene (~50%); cumene (isopropyl benzene) (~20%); cyclohexane
(~10%); and nitrobenzene (~10%). These
four chemicals are then in turn used in making many industrial and consumer products. Benzene’s use is growing (estimated in the 3
to 4% range annually) as demand for the many industrial and consumer products (made
from those four chemicals) grow.
Benzene’s use as a solvent is decreasing significantly as
benzene needs to handled cautiously, due to its exposure limits for health
reasons.
Benzene is derived from petroleum using primarily one of two
processes: steam cracking (~40% of benzene produced) and catalytic cracking
(~40%). Benzene is also made from methyl
benzene (toluene) (~20% of benzene produced).
Methyl benzene is a by-product in the production of gasoline from
petroleum.
Prices. Global
benzene 2019 metric ton (mt) prices appearing on the Internet are mostly in the
$700 to $800 per mt range. Benzene
prices can vary considerably over short periods as the prices of the petroleum
from which it is derived and the prices of the chemicals, which benzene is used
to make, change. These prices depend on
many supply, demand, and other factors, causing the prices to change
frequently.
Production. Global
benzene 2019 production estimates are in the high 40s to low 50s million mt
range. Assuming a 2019 average price for
benzene of $750 per mt (see prices above) and an estimated 2019 production of 50
million mt, estimated global revenues from benzene sales in 2019 are around $38
billion ($750 per mt times 50 million mt).
