What is the density of ethyl acetate?

Ethyl acetate (Ethyl acetate) is a common organic solvent, which is widely used in chemical, paint, paint, food and fragrance industries. Understanding the physical properties of ethyl acetate, especially its density, is essential for chemical experiments, industrial applications, and product formulation design. What is the density of ethyl acetate? This article will introduce the density of ethyl acetate in detail and analyze its changes under different conditions.

Ethyl acetate standard density

Ethyl acetate has a density of approximately 0.902g/cm³ at normal temperature and pressure. This density value shows that ethyl acetate is lighter than water (density 1.0g/cm³), so it is insoluble in water, but it can be mixed with many organic solvents. The low density of ethyl acetate allows it to exhibit good solubility in many solvent systems.

In practical applications, the density of ethyl acetate will be affected by temperature and pressure. Generally speaking, as the temperature increases, the volume of ethyl acetate will expand, resulting in a slight decrease in its density. Therefore, when accurately measuring the density of ethyl acetate, it is necessary to consider the specific temperature conditions.

TEMPERATURE EFFECT ON ETHYL ACETATE DENSITY

Temperature is a key factor affecting the density of ethyl acetate. As the temperature increases, the distance between molecules increases, the volume of matter usually expands, and the density decreases accordingly. Specifically, at 20°C, the density of ethyl acetate is 0.902g/cm³, while at 40°C, the density decreases slightly, reaching 0.888g/cm³. Therefore, it is very important to accurately measure the density of ethyl acetate at different operating temperatures.

In industrial applications, changes in the density of ethyl acetate are often used to adjust formulation ratios or to optimize the efficiency of solvent use. Therefore, many chemical plants monitor the temperature in real time during the production process to ensure the quality of the product and the stability of the production process.

Ethyl acetate-Density measurement method

To accurately determine the density of ethyl acetate, there are usually several methods to choose from. Common density measurement methods include:

1. pycnometer method: this is the most commonly used density measurement method, by adding a certain volume of ethyl acetate into the pycnometer, and then weighing the total mass of the bottle, using the formula to calculate the density. This method is suitable for small-scale measurements in the laboratory.

2. Vibrating tube density meter: This device uses the vibration frequency change of the liquid in the vibrating tube to measure the density. It has high accuracy and is suitable for industrial applications that require high accuracy.

3. Buoyancy method: The density of ethyl acetate can be obtained indirectly by measuring the change in the buoyancy of ethyl acetate in a liquid of known density. This method is suitable for coarser measurements.

In either case, it is necessary to ensure that changes in temperature are taken into account when measuring, as temperature has a significant effect on density.

Ethyl acetate density versus other solvents

In the chemical industry, ethyl acetate is often used with other solvents, so it is also important to understand the density difference between it and other commonly used solvents. For example, ethyl acetate has a lower density than water, but higher density than some common organic solvents, such as ethanol (about 0.789g/cm³ density). This means that when the solvent is mixed, ethyl acetate may float on the upper layer of the solvent, affecting the mixing effect.

Ethyl acetate also has a higher density than some low-density solvents, such as methylene chloride (density of about 1.33g/cm³). These physical properties determine its role and selectivity in different solvent systems. Therefore, when choosing ethyl acetate as a solvent, it is very important to consider the density factor.

Summary

The density of ethyl acetate is approximately 0.902g/cm³, but will vary with temperature. For the chemical industry and laboratories, it is very important to understand the density of ethyl acetate, because it directly affects the efficiency of solvent use, formulation design and optimization of reaction conditions. In practical applications, the density of ethyl acetate needs to be adjusted and measured according to specific temperature and pressure conditions to ensure product quality and stability of the production process. If you are still wondering "what is the density of ethyl acetate", you can use the above measurement method to determine in detail to ensure that you get an accurate value.
