Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower. Heat is then employed in the separating tower to separate the butadiene. It is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry.
Thionyl chloride is sometimes confused with sulfuryl chloride, SO2Cl2, but the properties of these compounds differ significantly. Sulfuryl chloride is a source of chlorine whereas thionyl chloride is a source of chloride ions.
Beryllium Oxide is a white colored, crystalline, inorganic compound that emits toxic fumes of beryllium oxides upon heating. Beryllium oxide is widely used in industry due to its low density and high thermal and electrical conductivity. It is used in high-technology ceramics, electronic heat sinks, electrical insulators, high-power devices, high-density electrical circuits, microwaves, X-ray windows, nuclear reactor fuels and for various aerospace and military applications. Inhalation exposure to its dust irritates the nose, throat and lungs and can cause pneumonitis.
Benzoyl Peroxide is a peroxide with antibacterial, irritant, keratolytic, comedolytic, and anti-inflammatory activity. Upon topical application, benzoyl peroxide decomposes to release oxygen which is lethal to the bacteria Proprionibacterium acnes. Due to its irritant effect, benzoyl peroxide increases turnover rate of epithelial cells, thereby peeling the skin and promoting the resolution of comedones. Benzoyl peroxide is used in the treatment of acne vulgaris.
