Liquid sulfuric acid is the most commonly used chemical, that’s why sulfuric acid can refer as universal chemical or king of chemicals. Liquid industrial grade raw materials sulfuric acid used as raw material or processing agent in a wide range of applications. Over one million tons of sulfuric acid is made each year in the UK alone, with an additional 40 million tones being produced in the USA. Annual worldwide production of sulfuric acid is around 180 million tons. Industrial grade sulfuric acid is available in many weight percent, ranging from electrolyte grade (33%) for batteries, to 93%, 98%, and 20-22% fuming oleum containing excess dissolved sulfur trioxide. The grade most often shipped is 93%.
As a highly important chemical compound, raw materials sulfuric acid is used in the manufacturing process of several well-known chemicals including hydrochloric acid, nitric acid, phosphoric acid, and many other industrial chemicals.
The process of refining crude oil requires the use of an acid as a catalyst and industrial grade liquid sulfuric acid is often used for this purpose. It is used in an SAAU or sulfuric acid Alkylation Unit.
"Pickling" is a term used to describe the treatment of metals to remove impurities, rust, or scale from the surface, such as in steel making. Today, the use of sulfuric acid for this purpose has decreased a little as the industry now favors the use of hydrochloric acid. Although hydrochloric acid is more expensive than raw materials liquid sulfuric acid, it produces results more quickly and minimizes the loss of base metal during the pickling process.
The manufacturing of rayon
The textile Rayon is made from cellulose fibers derived from wood. These are dissolved in a solution of Tetra Amine Copper (II) to produce a thick blue liquid which is then injected into raw materials industrial grade liquid sulfuric acid to form Rayon fibers. Rayon is a good semi-synthetic textile and can rival silk for drape and luster. Indeed, it is sometimes referred to as "art silk". It is easily dyed, and the fabric is soft, cool, and smooth. However, unlike silk, Rayon does not insulate body heat so is perfect for use in humid and hot countries.
The manufacturing of lead-acid type batteries
Sealed-unit lead-acid type batteries are used in the automotive industry for cars and trucks. Sealed-unit lead-acid type batteries were invented in 1859 by Frenchman Gaston Plants. sulfuric acid is used in a dilute form to act as an electrolyte to allow the flow of electrons between the plates in the battery. Sulfuric acid used in this way is commonly called Battery Acid. It can vary in strength according to the battery manufacturer but is generally between 28 to 32 percent or between 4.2 to 5 Molar.
Potato farmers employ specialist contractors to spray their fields of potatoes before harvesting so that the green tops die back and blacken within a day or two. This helps to dry out the stem and prevents them from becoming tangled in the harvesting equipment. The usual method of spraying potato tops is with a solution of raw materials industrial grade sulfuric acid.
The manufacturing of medicines
Chemotherapy drugs are used to treat various types of cancer. Cancer cells are more sensitive to DNA damage than normal cells so in chemotherapy treatment cancer cells are destroyed by damaging their DNA. This process is known as alkylation of DNA and a type of drug known as alkylating antineoplastic agents are used. Sulfuric acid is used in the manufacturing process of such drugs
