1.thin, clear or translucent, and flexible plastic sheet or strip that will accept printing ink. Acetate is used for the production of overlays, camera-ready proofs, and other types of graphics. The material is also used in the preparation of sequences in animated films. Each strip of the sequence is printed on a separate strip of acetate, called a cel.

2.material from which a phonograph disc is made.

1. a salt of acetic acid. n 2. short for cellulose acetate, the film base for x-rays.

A salt of acetic acid.

• a. base — cellulose acetate sheet used as support or base for x-ray film.
• a. tape slide — a method of collecting ectoparasites such as mites, lice or fleas, and their eggs, for diagnostic purposes by pressing the sticky side of the tape against the skin and haircoat and applying the tape to a glass slide which is then examined microscopically.

acetate anion

acetate ester

An acetate (IUPAC name: ethanoate) is either a salt or an ester of acetic acid. Its formula is written both as CH₃CO₂^- and C₂H₃O₂^-. Chemists abbreviate acetate as OAc⁻ and AcO⁻. Thus HOAc is the abbreviation for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate.^[1] Acetate is a common anion in biology.

Salts

The acetate anion, [CH₃COO]⁻, is a carboxylate. It is the conjugate base of acetic acid. The acetate ion is formed by the deprotonation of acetic acid:

CH₃COOH ⇌ CH₃COO⁻ + H⁺

Esters

An acetate ester is an ester of acetic acid, with the general formula CH₃CO₂R, where R is an organyl group. "Acetate" is also jargon for 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.
