what is the molecular formula and chemical structure of butyl acrylate?

Butyl acrylate is a common organic compound, which is widely used in chemical industry. This article will analyze the molecular formula and chemical structure of n-butyl acrylate in detail to help readers better understand its chemical characteristics.

Basic concept of 1. n-butyl acrylate

Butyl acrylate (Butyl Acrylate) is a kind of acrylate compound, which is formed by condensation of acrylic acid and n-butanol. Because of its excellent chemical and physical properties, it has been widely used in coatings, adhesives, plastics and other fields.

2. Formula of n-Butyl Acrylate

the molecular formula of n-butyl acrylate can be directly derived from its chemical structure. The molecular formula of acrylic acid is C3H4O2, and the molecular formula of n-butanol is C4H9OH. In the condensation reaction, the hydroxyl group of acrylic acid and the hydroxyl group of n-butanol are removed from one molecule of water to produce n-butyl acrylate. Thus, the formula for n-butyl acrylate is:

C7H10O2

this indicates that the compound is composed of 7 carbon atoms, 10 hydrogen atoms and 2 oxygen atoms.

Chemical structural formula of 3. n-butyl acrylate

the chemical structural formula of n-butyl acrylate can be described by the position of the functional group and the connection mode. Its structure consists of the following parts:

1. acrylic group: Acrylic group (CH2 = CHCOO-) is the core structure of n-butyl acrylate, which contains a double bond (C = C) and an ester group (COO).
2. n-butyl chain: The n-butyl chain (-O-C4H9) is connected to the acrylic group through an ester bond. The introduction of the n-butyl chain makes the molecule of n-butyl acrylate have a certain degree of hydrophobicity and flexibility.

The complete chemical structure of n-butyl acrylate can be expressed:

CH2 = CHCOO-C4H9

or expressed in a clearer structural formula:

properties and Applications of 4. n-Butyl Acrylate

1. chemical properties n-Butyl acrylate is a colorless liquid with a slight ether odor. It has good solubility in water and most organic solvents, but is insoluble in strong acids and alkalis.

2. Physical Properties n-Butyl acrylate has a boiling point of about 165°C and a density of about 1.02g/cm³. These properties give it important applications in the formulation of coatings and adhesives.

3. Application areas Butyl acrylate is widely used in the manufacture of acrylic resin, polyurethane, epoxy resin and other materials. It can also be used as a plasticizer, solvent and reactive monomer, and play an important role in coatings, inks, adhesives and other fields.

Synthesis and Storage of 5. n-Butyl Acrylate

the synthesis of n-butyl acrylate generally employs the condensation reaction of acrylic acid and n-butanol under acidic or basic conditions. In order to ensure the smooth progress of the reaction, it is usually necessary to add a catalyst and carry out the reaction at an appropriate temperature and pressure.

Butyl acrylate should be stored in a cool, well-ventilated place, away from fire and oxidant. Due to its flammability, safety needs to be paid attention to during storage and transportation.
