butyl acrylate boiling point, melting point and density are what?

n-Butyl acrylate is an important chemical raw material, widely used in coatings, adhesives, plastics and other fields. Understanding its physical properties, such as boiling point, melting point and density, is important for production and application. This paper will analyze these key physical properties of n-butyl acrylate in detail.

1. the boiling point of n-butyl acrylate

The boiling point of n-butyl acrylate is one of the important parameters in its physical properties. In general, the boiling point reflects the volatility of a substance at a particular pressure. The boiling point of n-butyl acrylate is approximately 165°C. This property keeps it liquid at room temperature, but volatilizes easily when heated, which is very useful in practical applications.

The boiling point is closely related to the molecular structure. The n-butyl acrylate molecule contains ester groups, which makes the molecules form a strong intermolecular force through hydrogen bonds, thereby increasing the boiling point. The carbon chain length of a molecule also affects the boiling point, with a longer carbon chain usually meaning a higher boiling point.

In practical applications, the boiling point characteristics of n-butyl acrylate make it an ideal choice for the preparation of solvents and coatings. For example, in coating formulations, n-butyl acrylate can be used as a solvent to help evenly disperse pigments and resins while providing good coating film performance.

2. the melting point of n-butyl acrylate

The melting point of n-butyl acrylate is another critical parameter in its physical properties. The melting point is the temperature at which a substance changes from a solid state to a liquid state. The melting point of n-butyl acrylate is about -50°C. This feature allows it to remain liquid at low temperatures and has good fluidity.

The melting point is closely related to the polarity of molecules and intermolecular forces. The ester group in the molecule of n-butyl acrylate gives it a certain polarity, but its polarity is lower than that of carboxylic acid compounds. This lower polarity makes the intermolecular forces weaker, thereby lowering the melting point.

In practice, the melting point characteristics of n-butyl acrylate enable it to adapt to a wide temperature range. For example, in cold areas, n-butyl acrylate can be used as a base material for an adhesive to keep the adhesive performance from being degraded by low temperatures.

3. of n-butyl acrylate density

The density of n-butyl acrylate is another important parameter in its physical properties. Density reflects the mass per unit volume of matter, usually in g/cm³. The density of n-butyl acrylate is about 1.05g/cm³, which is slightly higher than the density of water (1g/cm³) at room temperature. This property makes it less soluble in water, but has good solubility in organic solvents.

The density is closely related to the structure and chemical composition of the molecule. The n-butyl acrylate molecule contains ester groups and other carbon chain structures, and its molecular weight is moderate, so the density is moderate. Changes in temperature also affect density. As the temperature increases, the volume of n-butyl acrylate may expand, resulting in a slight decrease in density.

In practical applications, the density characteristics of n-butyl acrylate make it an ideal choice for formulating low-density materials. For example, in lightweight coatings and thermal insulation materials, n-butyl acrylate can be used as a base material to reduce the density of the overall material and improve its thermal insulation performance.

4. Summary

The boiling point, melting point and density of n-butyl acrylate are important parameters in its physical properties, which together determine its performance and use in practical applications. n-Butyl acrylate has a boiling point of about 165°C, a melting point of about -50°C and a density of about 1.05g/cm³. These properties make it have a wide range of applications in coatings, adhesives, plastics and other fields. Understanding these physical properties will help to better play the advantages of n-butyl acrylate and meet the needs of different industries.
