Introduction

Main Entry: Ester

isobutyl acetate (isobutyl acetate), also known as "isobutyl acetate", is the esterification product of acetic acid and 2-butanol, colorless transparent liquid at room temperature, miscible with ethanol and ether, slightly soluble in water, flammable, with mature fruit aroma, mainly used as a solvent for nitrocellulose and lacquer, as well as chemical reagents and flavoring.

isobutyl acetate has typical properties of esters, including hydrolysis, alcoholysis, aminolysis; Addition with Grignard reagent (Grignard reagent) and alkyl lithium, reduced by catalytic hydrogenation and lithium aluminum hydride (lithium aluminum hydride); Claisen condensation reaction with itself or with other esters (Claisen condensation). Isobutyl acetate can be qualitatively detected with hydroxylamine hydrochloride (NH2OH · HCl) and ferric chloride (FeCl ), other esters, acyl halides, the anhydride will affect the assay.

Application

Isobutyl acetate is a widely used ester solvent valued for its moderate evaporation rate, excellent solvency, and pleasant fruity odor. In the coatings industry, it is a key component in automotive refinish paints, nitrocellulose lacquers, and acrylic enamels, providing good flow and leveling properties. It is also employed in the formulation of printing inks for flexography and gravure, where it enhances pigment wetting and adhesion to substrates. In the flavor and fragrance sector, isobutyl acetate imparts sweet, banana, and rum like notes to confectionery, baked goods, and beverage flavors, and is used as a top note in perfumery for fruity and tropical accords. As a cleaning agent, it dissolves oils, greases, and resins in industrial degreasers and electronic parts cleaners. It also serves as a solvent for textile finishes, leather coatings, and nail polish removers. In adhesive formulations, it improves viscosity and drying characteristics. Additionally, isobutyl acetate is used as an extraction solvent for pharmaceuticals and natural products, and as a diluent in pesticide emulsifiable concentrates. In the production of cellulose esters, it acts as a plasticizer and processing aid. Its low water miscibility and good chemical stability make it suitable for use in printing plate cleaners and lithographic fountain solutions.

FAQ

Q1 How should isobutyl acetate be stored safely?
A Store in a cool, dry, well ventilated area away from ignition sources and strong oxidizers. Keep container tightly sealed. Shelf life is 24 months under recommended conditions.

Q2 What purity grades do you supply?
A Standard grade is 99.0 percent by GC. We also offer 99.5 percent grade for high end flavor applications and electronic cleaning.

Q3 Is isobutyl acetate miscible with water?
A Slightly soluble in water (about 0.7 g per 100 mL). Fully miscible with alcohols, ethers, ketones, and aromatic hydrocarbons.

Q4 Do you provide sample quantities for formulation development?
A Yes, free samples of 500 mL are available for qualified US companies. Shipping fee applies for small quantities.

Q5 What are the common impurities in isobutyl acetate and how do you control them?
A Key impurities include isobutanol, acetic acid, and water. Our specification limits isobutanol below 0.2 percent and acid value below 0.1 mg KOH per g.

Q6 Can you supply isobutyl acetate with a specific evaporation rate matching a competitor?
A Yes, we can adjust our product to match evaporation rate curves by blending with other esters. Please provide your target specification.

Q7 Is isobutyl acetate suitable for food contact coatings?
A Please request our regulatory package. It complies with certain FDA indirect additive regulations (21 CFR 175.300). Contact our compliance team for your specific end use.
