Ethyl Acetate Density: A Comprehensive Analysis and Its Influencing Factors
Ethyl Acetate (EA) is an important organic compound widely used in solvents, coatings, pharmaceuticals and flavours industries. In these applications, the density of Ethyl Acetate is a key parameter that directly affects its use and performance optimisation. In this article, we will discuss in detail the knowledge of ethyl acetate density and analyse its influencing factors to help relevant practitioners better understand and apply this compound.
What is Ethyl Acetate Density?
The density of ethyl acetate refers to the mass per unit volume of ethyl acetate at a certain temperature and pressure. Typically, the density of ethyl acetate is expressed in grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). Based on data from standard conditions, the density of ethyl acetate is approximately 0.897 g/cm³. This means that the mass of 1 cubic centimetre of ethyl acetate is approximately 0.897 grams at room temperature and pressure.
Importance of Ethyl Acetate Density
Ethyl acetate density is one of the crucial parameters in chemical production. In industrial applications, density directly affects the fluidity of solvents, their ability to dissolve, and the proportioning of mixtures. For example, in paint manufacturing, the density of ethyl acetate affects the viscosity and levelling of the paint, which in turn affects the quality of the final product. In the pharmaceutical industry, the density of ethyl acetate also has a significant effect on solubility and reaction rates in drug synthesis.
Factors affecting the density of ethyl acetate
Temperature: Temperature is one of the main factors affecting the density of ethyl acetate. As the temperature increases, the molecular spacing of ethyl acetate increases, which leads to a decrease in density. Usually, chemical engineers will strictly control the temperature in experiments and production to ensure that the density of ethyl acetate is stabilised within the desired range.

Purity: The purity of ethyl acetate is also an important factor in its density. If ethyl acetate contains impurities, the density of these impurities is different from that of pure ethyl acetate and may cause the overall density of the mixture to deviate from the standard value. Therefore, it is vital to ensure the purity of ethyl acetate in practice.

Pressure: Although the effect of pressure on the density of a liquid is relatively small, the density of ethyl acetate will change somewhat under high pressure. Usually, as the pressure increases, the molecules of the liquid are compressed and the density increases.

How is the density of ethyl acetate measured?
Methods of measuring the density of ethyl acetate usually include the specific gravity bottle method, the densitometer method, and the vibrating tube method. Among them, the specific gravity bottle method is widely used for laboratory measurements due to its high accuracy and reliability. The densitometer method is more commonly used in industrial sites because of its simplicity and ability to monitor density changes in real time. For high-precision requirements, the vibrating tube method is also often used, which uses the change in vibration frequency of the liquid in the vibrating tube to accurately measure the density.
Conclusion
Ethyl acetate density is a critical parameter in the chemical industry, affecting everything from solvent use to final product quality. Understanding and controlling the density of ethyl acetate can help chemical industry practitioners to better optimise their production processes and improve the performance and stability of their products. By analysing the effects of factors such as temperature, purity and pressure on the density of ethyl acetate, practitioners are able to develop production processes in a more scientific manner to ensure a high quality output.
