|Product name||perfluoroheptanesulfonic acid|
CAS No. 375-92-8 is a cyclohexanone, an aromatic ketone that is an intermediate component of reactive dyes, and industrial coatings and varnishes. As a reactive dye precursor, it is used for manufacturing synthetic leather, fashion clothes, and other textile finishing products with bright color and fastness. As a component of varnishes and coatings, it is used to coat paper and wood to protect them from moisture and corrosion. In organic synthesis, it is used as a starting material to synthesize caprolactam, sylvacur, and acrylate monomers.
CAS No. 375-92-8, usually in liquid form, appears as a colorless and odorless low-viscosity liquid, miscible in ether, ethyl acetate, and benzene, and slightly soluble in most organic solvents. The melting point of 375-92-8 is 1.7 degrees Celsius, and the boiling point 198.3 degrees Celsius. It undergoes low-temperature oxidation with good stability, but can be decomposed when salted. When heated to high temperature and open to air, it may form explosive compounds.
CAS No. 375-92-8 is mainly produced by separating the reaction liquid of acetaldehyde and formic acid or oxidative carbonylation of cyclohexene. The quality of CAS No. 375-92-8 varies with the production methods and properties. To ensure the quality of finished products, all the intermediate products involved, such as raw materials, catalysts, etc., should be strictly tested.
CAS No. 375-92-8 is largely used in the engineering and chemical industry due to its stable quality and good reactivity in organic acid-alkali system, so great caution should be taken when dealing with CAS No. 375-92-8, as any negligent operation might cause harm.
