Sulphuric Acid uses are many and varied. In brief terms, they include:-
- Sulphuric Acid uses in the manufacture of Phosphoric Acid
- Sulphuric Acid uses in the manufacture of Phosphate fertilizers
- Sulphuric Acid uses in the manufacture of Trisodium Phosphate for detergents
- Sulphuric Acid uses in the manufacture of iron and steel to remove rust or scale
- Sulphuric Acid uses in the manufacture of Aluminium Sulphate
- Sulphuric Acid uses in coagulation of paper pulp fibres into a usable surface
- Sulphuric Acid uses in the manufacture of Aluminium Hydroxide which is used as a filter in water treatment plants
Sulphuric Acid uses to make Hydrochloric Acid via the Mannheim Process- Sulphuric Acid uses as a catalyst in the production of Nylon
- Sulphuric Acid uses in the petro-chemical industry as a catalyst in the production of iso-octane (the octane rating in petrol)
- Sulphuric Acid is used in diluted form as the acid in lead-acid batteries (Battery Acid)
- Sulphuric Acid is used in the production of Hydrogen
Uses in Detail
As can be seen from the list above, Sulphuric Acid uses are numerous and Sulphuric Acid has been used in industry for many years. Sulphuric Acid is classed as an important commodity chemical and the amount of sulphuric acid used by a country is a good general indication of that country’s industrial development. Industrially developed countries will broadly have a higher usage of Sulphuric Acid than countries with little industrialisation.
The major use of Sulphuric Acid is for the production of Phosphoric Acid which, in turn, is used for the manufacture of Phosphate fertilizers. Phosphoric Acid is produced when Sulphuric Acid is manufactured using the ‘wet method’ of manufacturing.
Sulphuric Acid is also used in the manufacture of Trisodium Phosphate which, in turn, is used in the manufacture of detergents. Again, Trisodium Phosphate is produced when Sulphuric Acid is manufacture using the ‘wet method’ of manufacture.
Vast quantities of Sulphuric Acid are used in the iron industry and steelmaking. Sulphuric Acid removes oxidation, scale and rust from sheet metal. As such, Sulphuric Acid is a very important raw material of the motor industry.
Sulphuric Acid is used in the manufacture of Aluminium Sulphate. The addition of small amounts of soap on paper fibres helps to coagulate paper pulp fibres into a usable surface.
Sulphuric Acid is widely used in the manufacture of Aluminium Hydroxide which is used as a filter in water treatment plants. The use of Sulphuric Acid in this way helps to filter out impurities in water and to improve the taste of water.
Sulphuric Acid has many other important roles to play in industry and is widely used in other manufacturing processes. For example, a diluted form of Sulphuric Acid is the acid used in ‘battery acid’ for lead-acid batteries. Sulphuric Acid is used to make Hydrochloric Acid via the Mannheim Process. Sulphuric Acid is used as a catalyst in the production of Nylon, by converting cyclohexanoneoxime to captolactam. The petrochemical industry uses huge quantities of Sulphuric Acid which acts as a catalyst in the production of iso-octane which is the octane rating in petrol.
So, as the above illustrates, industrialised countries rely heavily on Sulphuric Acid as one of the most important chemical acids. Sulphuric Acid is commonly known with a ‘ph’ spelling in the United Kingdom and Europe, whilst Sulfuric Acid, with an ‘f’ is the preferred spelling in the Americas and the rest of the world. The product is exactly the same with either spelling. World production of Sulphuric Acid can be measured in millions of tonnes.
Sulphuric Acid is also known as Vitriol, Oil of Vitriol, Spirit of Vitriol, Sulphuric Acid Fuming and its chemical name is H2SO4. All these names refer to the same product.
