What industrial chemical is made in the largest quantity?
----------------------------------------------------------------------
Of all the products of the chemical industry, the one made in the
largest quantity is sulfuric acid or hydrogen sulfate (H2SO4). In
the US, about 40 million tons are produced every year.
In its pure form, sulfuric acid is an oily liquid, also known as oil
of vitriol. Pure sulfuric acid is very dangerous because it reacts

is usually sold in a dilute solution, which is much easier to work
with.
Sulfuric acid is used in a wide variety of processes in almost every
major industry. About 65% of it is used to make phosphate
fertilizers. It is also important in the manufacture of explosives,
dyes, paper, glue, and lead-acid batteries.
