Description
Application
It is used widely in laboratories as a solvent reagent and in the preparation of chemical compounds. Acetic acid glacial is also used in the manufacture of various chemicals like acetate esters acetic anhydride and acetic acid salts. It finds application in industries such as food pharmaceuticals and agriculture.
Purpose
Its primary purpose is anhydrous acid catalysis (pKa 4.76) in water-sensitive reactions like esterification and acetylation leveraging dimer formation via strong hydrogen bonding and high purity excluding water interference.
General Description
Acetic acid glacial is a highly concentrated form of acetic acid typically containing over 99% pure acetic acid. It is called glacial due to its ability to freeze at temperatures slightly below room temperature forming crystals.
