acid) is the colorless water absorbant liquid, the solidification
point is 16.7 °C (62 °F), after the coagulation, is the clear
crystal. Although according to ethanoic acid in peroxide solution
dissociation ability it is weak acid, but the ethanoic acid has
corrosiveness, its steam cross-eye and the nose have the irritant
function. The ethanoic acid is one kind of simple carboxylic acid,

synthetic fibers and fabric. In the family, the ethanoic acid
dilute solution often serves as the cleaning media. Food industry
