What is n-Butyl Acetate CAS 123-86-4?

n-Butyl Acetate is a clear, colourless ester solvent with the chemical name butyl ethanoate and formula C6H12O2. It is supplied as a medium-volatility solvent for industrial coatings, printing inks, adhesives and chemical-process applications.

Are n-Butyl Acetate and Butyl Ethanoate the same material?

Yes. n-Butyl acetate and butyl ethanoate are names for CAS 123-86-4. They should not be confused with isobutyl, sec-butyl or tert-butyl acetate, which are different isomers with different boiling points and evaporation behaviour.

What are the key physical properties of n-Butyl Acetate?

n-Butyl Acetate has a boiling point of about 124-126 deg C, a density around 0.88 g/mL at 25 deg C and a freezing point near -73 to -78 deg C. It is only slightly soluble in water, with vapour density around four times that of air.

Which resins and applications is n-Butyl Acetate used in?

It is used in coatings, lacquers, varnishes, flexographic and gravure inks, and solvent-borne adhesives. It also performs well in nitrocellulose, cellulose-ether, acrylic, alkyd and selected vinyl-resin systems, as well as in specified reaction and extraction processes.

Which n-Butyl Acetate specifications should be checked before use?

Confirm purity, water, acidity, colour, distillation range and non-volatile matter against the intended solvent blend. The required limits should match the existing formulation because water tolerance, evaporation balance and residue sensitivity vary by coating or ink system.

Product Description

n-Butyl Acetate CAS 123-86-4 is butyl ethanoate, with EC 204-658-1 and molecular formula C6H12O2.

Synonyms: n-Butyl acetate; Butyl acetate; Butyl ethanoate; Acetic acid n-butyl ester.

CAS: 123-86-4.

Molecular formula: C6H12O2.

It is supplied as a clear, colourless liquid.

It is positioned as a medium-volatility ester solvent for industrial coatings, inks, adhesives and chemical processes.

The normal-butyl isomer is supplied specifically and is not substituted with isobutyl, sec-butyl or tert-butyl acetate.

It is used in coatings, lacquers and varnishes requiring an ester solvent component.

It is used in flexographic, gravure and other printing-ink formulations and in solvent-borne adhesives.

It works well in nitrocellulose, cellulose-ether, acrylic, alkyd and selected vinyl-resin systems.

It is also used in specified reaction and extraction processes.

Commercial grades commonly specify a boiling point of about 124-126 C, a density around 0.88 g/mL at 25 C and a freezing point near -73 to -78 C.

Confirm purity, water, acidity, colour, distillation range and non-volatile matter against the intended solvent blend.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from ignition sources.

Use suitable PPE and vapour control when handling the material to prevent inhalation and skin or eye contact.

Confirm packaging suitable for the liquid form and order quantity, and follow the current SDS.

Confirm grade, packaging, and specification as required.
