Isobutyl Acetate 99.5% Industrial Grade | CAS No. 110-19-0

Name: Isobutyl Acetate 99.5% Industrial Grade | CAS No. 110-19-0
Brand: Richnow Chem

This high-purity Isobutyl Acetate, with a concentration of 99.5% or higher, is a clear, colorless liquid with a characteristic fruity, ester-like odor reminiscent of pear or raspberry. It is produced through the esterification of isobutanol and acetic acid under strict quality control measures. Isobutyl acetate offers excellent solvency properties, a balanced evaporation rate, and low water miscibility, making it a valuable solvent in various industrial applications. It is particularly valued in the formulation of coatings, printing inks, adhesives, and flavoring applications where controlled evaporation and strong solvency are required.

Scope of Application
· Used as a solvent in nitrocellulose coatings, lacquers, and wood finishes due to its excellent resin compatibility and balanced evaporation；
· Applied in printing inks, including gravure and flexographic inks, where it provides good flow and leveling properties；
· Functions as an active solvent in adhesive formulations, particularly for packaging and pressure-sensitive adhesives；
· Serves as a process solvent in the extraction, purification, and synthesis of various organic compounds；
· Used in the production of artificial leather, photographic films, and nail polish removers；
· Employed as a flavoring agent in food and beverage applications (food-grade versions available upon request)；
· Utilized in cleaning agents and degreasers for industrial maintenance and parts cleaning.

Product Features

Isobutyl acetate is manufactured using continuous esterification and rectification processes, ensuring high purity and consistent quality across all batches. The product exhibits strong solvency for a wide range of polymers, including nitrocellulose, acrylics, alkyd resins, and vinyl resins. Its balanced evaporation rate (slower than ethyl acetate but faster than n-butyl acetate) provides excellent flow and leveling properties in coating applications while maintaining acceptable drying times. The branched molecular structure of isobutyl acetate offers slightly different solvency characteristics compared to its straight-chain counterpart, which can be advantageous in specific formulations. The low water miscibility enhances humidity resistance during application. The product is strictly tested using GC analysis to ensure it meets the highest industrial standards. Its pleasant, fruity odor makes it preferable in applications where worker exposure and end-user experience are considerations.

FAQ

What are the main differences between Isobutyl Acetate and n-Butyl Acetate?

Isobutyl acetate has a slightly faster evaporation rate and lower boiling point (118°C) compared to n-butyl acetate (126°C). It also exhibits a more pronounced fruity odor and slightly different solvency characteristics due to its branched molecular structure. In some resin systems, isobutyl acetate may offer better dilution ratio or different viscosity profiles. The choice between the two often depends on specific formulation requirements, including evaporation rate preferences and odor considerations.

Is Isobutyl acetate suitable for food and flavor applications?

Standard industrial grade isobutyl acetate is not intended for direct food contact. However, food-grade versions meeting specific purity and safety standards are available for flavoring applications. Please contact our technical team to discuss your specific requirements.

How does Isobutyl acetate compare to Methyl isobutyl ketone (MIBK)?

While both solvents offer similar evaporation rates, isobutyl acetate provides a milder, more pleasant odor profile compared to MIBK. It also offers different solvency characteristics, making it a potential alternative in formulations where reduced toxicity or improved odor is desired, though solvency power and resin compatibility should be verified for each specific application.
