Acetate

The acetate anion, [CH3COO], is a carboxylate and is the conjugate base of acetic acid. The acetate ion is formed by the deprotonation of acetic acid: An anion is an ion with negative charge. ... Structure of a carboxylic acid Carboxylic acids, also known as alkanoic acids, are organic acids characterized by the presence of a carboxyl group and have the general chemical formula R-C(=O)-OH, also written as R-COOH, where R is a hydrogen or an alkyl group. ... Within the Brønsted-Lowry (protonic) theory of acids and bases, a conjugate acid is the acid member, HX, of a pair of two compounds that transform into each other by gain or loss of a proton. ...

Acetate esters

An acetate ester is an ester of acetic acid, with the general formula CH3COOR, where R is an organyl group. In organic chemistry, a substituent is an atom or group of atoms substituted in place of a hydrogen atom on the parent chain of a hydrocarbon. ...


Acetate can also refer to cellulose acetate, especially fibres or other derived products such as the acetate disc used in audio record production. Cellulose acetate can be found in many household products. Cellulose acetate, first prepared in 1865, is the acetate ester of cellulose. ... In sound recording an acetate disc is a reference audio disc used during production of a gramophone record (e. ...


Notation in organic chemistry

In the field of organic chemistry the abbreviation Ac refers to the acetyl group. Hence, acetate can be written OAc or AcO and acetic acid, sodium acetate, and ethyl acetate can be denoted by HOAc, NaOAc, and EtOAc respectively. Organic chemistry is a specific discipline within chemistry which involves the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of chemical compounds consisting primarily of carbon and hydrogen, which may contain any number of other elements, including nitrogen, oxygen, halogens as well... Acetyl is the radical of acetic acid. ...

Sodium acetate, (also rarely, sodium ethanoate) is the sodium salt of acetic acid. ... R-phrases , , , S-phrases , , Flash point −4 °C Related Compounds Related carboxylate esters Methyl acetate, Butyl acetate Related compounds Acetic acid, ethanol Supplementary data page Structure and properties n, εr, etc. ...


Ac is also the symbol for the chemical element actinium, but confusion between actinium and the acetyl group is rare, since actinium has virtually no role in organic chemistry. The periodic table of the chemical elements A chemical element, or element, is a type of atom that is defined by its atomic number; that is, by the number of protons in its nucleus. ...
