Ethyl Isobutyrate

Ethyl isobutyrate is a branched-chain fatty acid ester formed from isobutyric acid and ethanol; it occurs naturally in strawberries, beer, and champagne. It appears as a colorless, volatile liquid with a sweet, rich, fruity aroma—resembling a blend of apple, pineapple, and grape scents. It is slightly soluble in water and miscible with most organic solvents, such as ethanol, diethyl ether, and acetone.

Physicochemical properties

Appearance and Odor: Ethyl Isobutyrate is a colorless, volatile liquid with a sweet, rich, fruity aroma-a complex scent reminiscent of apple, pineapple, and grape.
Boiling Point: 110.1–113°C (at atmospheric pressure).
Density: 0.865–0.87 g/cm³ (at 20°C); lighter than water.
Flash Point: 13–13.9°C (closed cup); classified as a flammable liquid with a moderate flash point.
Solubility: Slightly soluble in water; miscible with most organic solvents, such as ethanol, diethyl ether, and acetone.

Primary Uses

Food Flavor Formulation: Derived from food-grade flavoring agents permitted under GB 2760, Ethyl isobutyrate is widely used in the formulation of fruit-type flavorings, such as cream, strawberry, and cherry.-for applications in soft drinks, confectionery, and baked goods.
Fragrances for Consumer Products: Used in personal care products like perfumes and soaps to provide fruity top notes.
Industrial Solvents and Synthesis: Serves as a fast-drying solvent for nitrocellulose, resins, and coatings, as well as an intermediate in fine chemical synthesis.

Safety and Toxicology

Acute toxicity: Ethyl isobutyrate is classified as having low toxicity.; the intravenous LD₅₀ in mice is approximately 800 mg/kg.
Irritation: Vapors or mists are irritating to the eyes, mucous membranes, and upper respiratory tract; the liquid causes moderate skin irritation and has a defatting effect.
Fire and explosion hazards: Highly flammable; poses a severe risk of fire or explosion upon exposure to open flames, high heat, or strong oxidizing agents. Vapors are heavier than air and can travel to distant sources of ignition.
Protection requirements: Operations must be conducted in a closed system with adequate ventilation; keep away from sources of ignition and heat. Wear a self-priming filter-type respirator, chemical safety goggles, and anti-static work clothing.
