*Dibasic Ester (DBE )

Basic Definition

• Dibasic Ester (DBE) is a mixture of dibasic esters. It is mainly an environmentally friendly high-boiling point solvent composed of dimethyl succinate, dimethyl glutarate, and dimethyl adipate.

Physicochemical Properties

• Boiling Point Range: Its boiling point range is between 196 - 225°C, which makes it very useful in high-temperature reactions or processes that require solvents with higher boiling points. This relatively high boiling point helps reduce the emission of volatile organic compounds (VOCs) and is beneficial for environmental protection.

• Solubility: DBE has good solubility and can dissolve a variety of organic compounds such as polyester, polyurethane, and acrylic resin. It can be used as a solvent in coatings and ink formulations to help dissolve resin components and give coatings and inks good fluidity and coating performance.

• Density and Vapor Pressure: The density is approximately 1.09 - 1.12 g/cm³, and the vapor pressure is relatively low. At room temperature, the volatilization rate is slow, which helps reduce the loss of solvent during storage and use.

• Flash Point: The flash point is relatively high, generally around 100°C. This increases its safety during storage and use and reduces the risk of fire and explosion.

Production Process

• DBE is usually produced by esterification reaction of the corresponding dibasic acids (succinic acid, glutaric acid, adipic acid) with methanol under the action of a catalyst. During the reaction process, it is necessary to control the reaction temperature, pressure, and the ratio of reactants to ensure the production of high-quality DBE products.

Application Fields

• Coatings and Paints Industry: As a solvent, it can improve the fluidity, drying speed, and glossiness of coatings. It can also be used to dissolve and dilute resins so that coatings can better adhere to the coated object surface. And due to its good environmental performance, it helps reduce the VOCs content in coatings and meets environmental protection regulations.

• Ink Industry: Used in ink formulations, it can dissolve ink resins and adjust the viscosity and drying properties of inks so that inks can better transfer and adhere to printing materials such as paper and plastic films during the printing process.

• Cleaning Industry: Due to its good solubility, it can be used as a cleaning agent to clean oil and dirt on the surfaces of metals, plastics, and electronic equipment. It can effectively remove grease, wax, and other organic pollutants and is easy to volatilize after cleaning without leaving residues.

• Chemical Synthesis Field: As a reaction solvent or intermediate, it participates in some organic synthesis reactions. For example, in some polyester synthesis reactions, DBE can be used as a solvent and raw material to participate in the construction process of polyester chains. It can also be used as an extractant for separating and purifying organic compounds.

Appearance
Color
DBE (dibasic ester) is usually a colorless and transparent liquid. This colorless appearance gives it a great advantage in many applications with strict color requirements, such as in the coatings and ink industry, as it will not bring additional color interference to the final product.
State
It is in a liquid state with good fluidity. This is because its intermolecular forces and physical properties determine that it is liquid at normal temperature and pressure. This good fluidity makes it easy to be transported through pipelines, measured, and mixed in industrial production processes. In coating production, it can be easily mixed evenly with other components (such as resins, pigments, etc.) to ensure the consistency of coating quality.
