How does isobutyl acetate differ from n-butyl acetate?

They are structural isomers with different CAS numbers and evaporation behaviour. They can serve similar solvent roles, but resin compatibility, drying profile and final coating appearance should be checked before replacing one with the other.

What should be stated in an isobutyl acetate purchase specification?

State the required GC purity, water limit, acidity, APHA colour, non-volatile residue, distillation profile, package type and destination. These parameters are more useful than a generic statement of purity for a coatings or ink formulation.

Isobutyl Acetate CAS 110-19-0

Isobutyl acetate, also known as 2-methylpropyl acetate, CAS 110-19-0, is an ester solvent for coatings, printing inks, adhesives and process applications. Industrial grades are controlled by purity, water and acidity, with COA, TDS and SDS for the agreed solvent grade.

Product Description

Isobutyl acetate (CAS 110-19-0) is a clear ester solvent used in coating, ink, adhesive and extraction processes. Its practical role is determined by solvent strength, evaporation profile, water tolerance and resin compatibility. It is an isomer of butyl acetate, so the product name and CAS number must both be controlled in purchasing and formulation work.

1 Applications

2 Specification points

3 Handling

Applications

Coatings and lacquers where ester-solvent balance affects flow, levelling and drying.
Printing inks and adhesive formulations requiring compatibility with the selected resin system.
Reaction and extraction processes where an ester solvent is appropriate for the process design.
Industrial cleaning or thinner blends after compatibility and safety review.

Specification points

Specify GC purity, water, acidity, colour, non-volatile matter and distillation range. n-Butyl acetate and sec-butyl acetate are related isomers, but their properties and formulation behaviour are not identical.

Handling

Isobutyl acetate is a flammable solvent. Packaging, transport classification, storage, grounding and ventilation must follow the current SDS and the local rules governing the final use.
