Acetate
From Wikipedia, the free encyclopedia
- Acetate is also used to describe cellulose acetate
Acetate, or ethanoate, is the anion of a salt or ester of acetic acid. The acetate ion has the formula CH3COO− and CH3CO2 in organic chemistry and C2H3O2− is the conjugate base of acetic acid.
Acetate can also refer to cellulose acetate, especially fibers or other derived products such as the acetate disc used in audio record production. Acetate can be found in many household products.
[edit] Use in organic chemistry
In the field of organic chemistry the abbreviation Ac refers to the acetyl group CH3CO. Hence, acetate can be written -OAc such as HOAc, NaOAc, and EtOAc for acetic acid, sodium acetate, and ethyl acetate respectively.
