Ethyl acetate is a colorless, transparent, flammable liquid with a fruity aroma.
Ethyl acetate has low toxicity, is volatile, has a relative density of 0.902, a melting point of -83°C, and a boiling point of 77°C. It is slightly soluble in water and soluble in most organic solvents such as alcohol, ketone, ether, and chloroform. Its vapor and air can form Explosive mixture, meeting fire, high heat can cause combustion and explosion.

Crystal structure: equiaxed crystal system, cube, octahedron or dodecahedron. Colorless crystals or white powder containing impurities in natural ore with a greenish or purplish tinge. Glow when heated. Density 3.18g/cm3, melting point 1402℃, boiling point 2497℃, refractive index 1.434. Low toxicity. Extremely insoluble in water. Soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. When dissolved in aluminum salt and iron salt solution, a complex is formed, which reacts with hot concentrated sulfuric acid to produce hydrofluoric acid. Hydrogen fluoride can be prepared by reacting calcium fluoride with concentrated sulfuric acid in a lead container. Can form low eutectic with a variety of metal oxides.

Dioctyl phthalate (DOP), an organic ester compound, is a commonly used plasticiser.

Octanol, also known as n-octanol, is an organic compound, a colorless transparent oily liquid with a strong oily and citrusy smell, immiscible with water, but miscible with ethanol, ether, and chloroform. Octanol is mainly used to prepare dioctyl phthalate, dioctyl terephthalate, octyl acrylate, dioctyl azelate, dioctyl sebacate and other products; in addition, it can also be used as a solvent , plasticizer, antifreeze, lubricant, extractant, dispersant, stabilizer, fragrance and other products, used in refined oil, plastics, coatings, printing and dyeing, food processing, cosmetics and other fields.
