What is Ethyl Acetate CAS 141-78-6?

Ethyl Acetate is a fast-evaporating ester solvent with formula C4H8O2. It is supplied for packaging inks, industrial coatings, solvent-borne adhesives and cleaning or extraction processes that require a defined ester solvent.

Is Ethyl Acetate the same as ethyl ethanoate?

Yes. Ethyl ethanoate is the systematic name for Ethyl Acetate, and both names refer to CAS 141-78-6. The names do not indicate a different material or grade.

Can Ethyl Acetate replace n-Butyl Acetate or MEK in a formulation?

Not automatically. Ethyl Acetate evaporates much faster than n-Butyl Acetate, and although its boiling point is close to MEK, the solvency, water tolerance and odour balance are different. A replacement should be evaluated in the complete ink, coating or adhesive formulation.

Which Ethyl Acetate specifications should be checked before use?

Confirm purity, alcohol content, water, acidity, colour, distillation range and non-volatile matter against the solvent blend. The limits should match the packaging-ink, coating or adhesive process because drying speed, residue and water tolerance can affect the finished result.

Product Description

Ethyl Acetate CAS 141-78-6 is ethyl ethanoate, with EC 205-500-4 and molecular formula C4H8O2.

Synonyms: Acetic Acid Ethyl Ester; Ethyl Ethanoate; EA.

CAS: 141-78-6.

Molecular formula: C4H8O2.

It is supplied as a clear, colourless liquid.

It is positioned as a fast-evaporating ester solvent for packaging inks, industrial coatings and adhesive manufacture.

It is used as a blend component where a formulation needs a defined evaporation and resin-solvency balance, and is not assumed interchangeable with butyl acetate or ketone solvents.

It is used in flexible-packaging, gravure and flexographic ink systems.

It is used in industrial coatings, primers and lacquer formulations.

It is used in solvent-borne adhesives and laminating blends.

It is used in printing-ink, cleaning and extraction processes with a specified ester solvent.

Commercial grades commonly specify a boiling point of about 76.5-77.5 C, a density near 0.90 g/mL and a vapour pressure around 73 mm Hg at 20 C.

It is only partially soluble in water, at about 80-85 g/L at 20 C.

Confirm purity, alcohol content, water, acidity, colour, distillation range and non-volatile matter against the 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.
