Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid ...
In fact basic chemicals are chemical substances used as a starting material for the production of a wide variety of other chemicals; for this reason they are in general commodities, because they are highly demanded. Some examples of basic chemicals are: ethylene, benzene, chlorine and sulfuric acid. [7]
a highly corrosive, strong mineral acid with many industrial uses Hydrofluoric acid: valued source of fluorine, precursor to numerous pharmaceuticals; highly corrosive Hydrogen peroxide: an oxidizer commonly used as a bleach Imidazole: an organic compound; this aromatic heterocyclic is a diazole and is classified as an alkaloid: Isopropyl alcohol
Toxic, corrosive and foul smelling hydrogen sulfide (H 2 S) is the most common contaminant in biogas. If not separated, combustion will produce sulfur dioxide (SO 2) and sulfuric acid (H 2 SO 4), which are corrosive and environmentally hazardous., [24] Other sulfur-containing compounds, such as thiols may be present.
The important sulfur cycle is a biogeochemical cycle in which the sulfur moves between rocks, waterways and living systems. It is important in geology as it affects many minerals and in life because sulfur is an essential element (), being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in microbial respiration.

Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. [1]
This non-galvanic form of corrosion can occur when a metal is subjected to a hot atmosphere containing oxygen, sulfur ("sulfidation"), or other compounds capable of oxidizing (or assisting the oxidation of) the material concerned. For example, materials used in aerospace, power generation, and even in car engines must resist sustained periods ...
These gases are highly corrosive to any downstream equipment such as fans, ducts, and stacks. Two methods that may minimize corrosion are: (1) reheating the gases to above their dew point , or (2) using materials of construction and designs that allow equipment to withstand the corrosive conditions.
