1. Industrial solvent: it is used for coatings,adhesives, ethyl cellulose, artificial leather, linoleum colorants, artificialfibers and other products.
2. Adhesive: it is used for the production ofprinting ink and artificial pearls. As an extraction agent, it is used for theproduction of pharmaceuticals, organic acid and other products.
3. Raw material for spice: it is the main rawmaterial for pineapple, banana, strawberry and other fruit essence and whiskey,cream and other spices. It can be used for the production of spice, blending spiceand artificial essence for liquor.
4. Extractant: It can extract many compounds(phosphorus, tungsten, arsenic, cobalt) from aqueous solutions.
5. Organic solvent: it can be used as a referencesubstance for calibrating thermometers when separating sugars.
6. It can also be used as a cleaning agent for thetextile industry and an extractant for natural spicery, and is an important rawmaterial for the pharma-ceutical industry and organic synthesis.
7. It is an edible spice that is accepted accordingto GB2760-2014 and is mainly used for flavoring, persimmon deastringency,making granules or tablets of spicery, and brewing vinegar ingredients.

Ethyl acetate, with the chemical formula CH3COOCH2CH3, is a colorless liquid renowned for its sweet,fruity aroma reminiscent of bananas or pears. As a common ester, it possesses a molar mass of approximately 88.11 g/mol and a density of 0.902g/mL at 20 °C, making it less dense than water. It has a low freezing point of -83.6 °ºC (-118.5 F) and boils at 77.1 °C (170.8 F), remaining liquid under typical room conditions. Slightly soluble in water but highly miscible with organic solvents like ethanol and acetone, it exhibits balanced solubility that enhances its utility across industries.

Ethyl acetate serves as a fundamental solvent in numerous applica-tions, including paints, lacquers, and varnishes, where it effectively dissolves resins and contributes to smooth coating finishes. It is also a key component in the production of adhesives, printing inks, and artificial leather, as well as a extraction solvent in pharmaceuticals and food processing (e.g., decaffeinating coffee). In the food and fragrance industries, it acts as a flavoring agent and aromatic component, adding subtle fruity notes to products. However, its flammable nature requires strict safety measures, such as avoiding open flames and ensuring proper ventilation. Prolonged exposure to its vapors may cause eye irritation or dizziness, necessitating protective gear during handling and storage.
