Uses of sulfuric acid

Sulfuric acid is primarily used as a raw material in the inorganic chemical industry and is known as the \"mother of inorganic chemicals.\" Industrially, sulfuric acid, hydrochloric acid, and nitric acid are referred to as the three major acids. The largest consumer of sulfuric acid is the fertilizer industry, where it is used to produce phosphoric acid, superphosphate, and sulfuric anhydride. The fertilizer industry in the Western world accounts for about 65% of sulfuric acid consumption. In China, the fertilizer industry also accounts for 50% to 60% of sulfuric acid usage. In the petroleum industry, sulfuric acid is used in the refining of products such as gasoline and lubricants, as well as in the alkylation of olefins to produce high-octane gasoline. The steel industry relies on sulfuric acid for pickling, in order to remove iron oxide scales from the surface of steel; this process is a necessary pretreatment step for operations such as rolling steel sheets, cold-drawing steel pipes, and galvanizing. In the non-ferrous metallurgy industry, sulfuric acid is used in wet processing methods to leach copper ore, uranium ore, and barium ore ； Electrolytic refining of metals such as copper, zinc, nickel, and cadmium requires the use of sulfuric acid to prepare the electrolyte. Hydrofluoric acid can be produced from fluorite and sulfuric acid (see chemical processing of fluorite); it forms the basis of the modern fluoride industry and is closely related to the nuclear and aerospace industries. In the production of materials such as nitrocellulose, RDX, nitroglycerin, and picric acid, sulfuric acid serves as an essential dehydrating agent in the nitration process. In the chemical fiber industry, sulfuric acid is used to prepare the spinning and setting baths for viscose fibers ； The production of vinylon requires sulfuric acid for acetalization ； In the production of nylon, sulfuric acid is used to dissolve **oximes in order to carry out Beckmann rearrangement. In the plastics industry, significant amounts of sulfuric acid are also required for the production of epoxy resins and polytetrafluoroethylene. In the dye industry, sulfuric acid is utilized in the manufacture of dye intermediates. When reacted with ilmenite, sulfuric acid produces titanium dioxide, an important white pigment. In 2006, China’s production of concentrated nitric acid was 1.77652 million tons, while the production of sulfuric acid was 48.6033 million tons. 2007: China’s production of concentrated nitric acid was 2.00885 million tons, while the production of sulfuric acid was around 52.8 million tons. China imports about 2 million tons of sulfuric acid each year for domestic use, making it a net importer of sulfuric acid. In 2008, China’s sulfuric acid production was approximately 60 million tons

It’s all like this: the price of sulfur used to be over 700 dollars, but now it’s around 50 dollars only. Its price has dropped even faster than that of stocks. Many companies that were afraid of further price increases during the surge in sulfur prices bought large quantities of sulfur through contracts, resulting in heavy losses. It’s been such hard work for over half a year, only to fall back to the pre-liberation era. One cannot work in isolation; it is necessary to look ahead with a developmental perspective. These days, production is market-driven, with decisions made based on market conditions.

Our factory also went through such a transition period; currently, the price of sulfuric acid is 150 yuan per ton

Affected by the financial crisis, the current price of 93% sulfuric acid in our company is 120 yuan per ton, and the enterprise is facing difficulties in sales

Sulfuric acid has extremely wide applications, as it is known as the \"mother of industries\"”

The low price of sulfuric acid is a boon for manufacturers that require large quantities of it.

Primarily used for drying and the production of synthetic fibers; a true \"mother of industry\"”
