Dibutyl Adipate(DBA)

Dibutyrate adipate (DBA) has a wide range of main application fields. In the field of industrial manufacturing, it has many uses. The first to bear the brunt is the field of coatings and inks. DBA can be mixed with plasticizers to make coatings more flexible and adherent. Such as ancient lacquer coloring, if you want the paint to last for a long time and the utensils are flexible and not easy to break, DBA type additives can play a big role. The paint film can still maintain good physical properties in different environments, resist dry cracking and wear resistance, just like the ancient lacquer has been rubbed over the years and the color remains the same. This is the power of DBA. Furthermore, it is also indispensable in the plastics industry. In the plastic processing process, the addition of DBA can improve the processing performance of plastics and enhance their plasticity and fluidity. Just like ancient pottery, the clay is cleverly reconciled to achieve the ideal shape. DBA makes plastics easy to shape, producing plastic products of different shapes, and endows plastic products with good low temperature performance. It is not easy to embrittle in cold seasons, even if the utensils do not crack in winter. In addition, in the field of artificial leather manufacturing, DBA, as a plasticizer, can give artificial leather a soft texture and simulate the touch and appearance of natural leather. Just like in ancient times when other leather was imitated, DBA makes the imitation more realistic and enhances the durability of artificial leather, making it last for a long time without damaging its quality. In the field of lubricants, DBA can be used as an additive to enhance lubrication, reduce friction and wear between mechanical parts, just like the ancient axle oiling, making the wheels rotate more smoothly, prolonging the service life of mechanical equipment, and ensuring the smooth operation of industrial production.

Dibutyrate adipate (DBA) has various physical properties. Its color is clear and transparent, like water, almost colorless, and pure in appearance. In terms of smell, it emits a faint and pleasant fragrance, which is not irritating, and feels mild when smelled. At room temperature, it is in a liquid state, with uniform texture and good fluidity. It flows like water without stagnation. The boiling point of DBA is quite high, about 340 ° C, which makes it capable of maintaining a liquid state at higher temperatures and is not easily vaporized. The melting point is relatively low, around -70 ° C, so it is difficult to condense and solidify under normal low temperature conditions. Its density is close to 0.966g/cm ³, which is slightly lighter than water. If it is co-located with water, it can float on the water surface. In terms of solubility, DBA exhibits good solubility in many organic solvents, such as ethanol and ether, which can be mutually soluble with it; however, its solubility in water is very small, and the two are difficult to blend. In addition, DBA has a moderate viscosity, neither too thick to cause difficult flow, nor too thin to lose its stability. This property makes it suitable for many industrial applications. It can be used as a plasticizer to improve material flexibility, or as a solvent in a specific chemical reaction system to assist in the reaction.

The chemical stability of adipate dibutyrate (DBA) is important for many applications. This compound has considerable chemical stability due to its chemical structure. In DBA molecules, the carboxyl group of adipic acid and the hydroxyl group of butanol condensate to form an ester bond. The characteristics of ester bonds are the cornerstone of its stability. Generally speaking, ester bonds are quite stable at room temperature without special chemical action, and are not easy to spontaneously cleave or participate in reactions. At room temperature, DBA can maintain its own structure for a long time, and rarely react with common components in the air, such as oxygen and nitrogen. Even in an atmosphere with a slight change in humidity, the degree of hydrolysis is extremely limited, because ester hydrolysis requires specific conditions, such as strong acid or strong base catalysis and high temperature. Furthermore, the alkyl chain of DBA also contributes to its stability. The long chain alkyl group of butyl imparts a certain spatial barrier to the molecule, which can prevent external reagents from approaching the ester bond, reduce the reactivity, and then improve the stability. However, it needs to be understood that although DBA has good chemical stability, the stability will also be affected under certain conditions. If there is a strong acid or strong base at high temperature, the ester bond will be hydrolyzed, resulting in the destruction of the molecular structure. Or in case of strong oxidants, it may initiate an oxidation reaction and affect its chemical stability.

When making adipate dibutyrate (DBA), there are several things to pay attention to during production. The first raw material. Pure adipic acid and n-butanol should be selected as materials. Adipic acid must be free of impurities and pure in color. Its quality is related to the purity and performance of DBA. Butanol also needs to meet standards, and the water content and impurities should be strictly controlled. If the raw materials are not good, the quality will be poor, or the color will be impure, the smell will be abnormal, etc. The second time is the reaction condition. If the temperature is high, this reaction often needs to be heated, but if the temperature is too high, the side reaction will produce a decrease in yield and increase in impurities; if the temperature is too low, the reaction will be slow, time-consuming and inefficient. Usually in the presence of a suitable catalyst, the temperature is controlled within a specific range to promote the smooth reaction and obtain the best yield and purity. The pressure cannot be ignored. Although it can be reacted under normal pressure, under specific circumstances, the pressure adjustment or the reaction will be in the direction of generating DBA. Furthermore, the choice and dosage of the catalyst are critical. Suitable catalysts can increase the rate of growth and yield. However, the dosage needs to be considered, too much will be costly, and may lead to post-treatment problems; too little will lead to poor catalytic effect. When used, it should be precisely prepared according to the scale and conditions of the reaction. Repeat, reaction equipment. The material must be acid and alkali resistant, because there may be acidic substances in the reaction. The equipment is also heavily sealed to prevent raw materials and products from escaping, ensuring safety and avoiding waste. The mixing device is good, so that the materials are fully mixed and the reaction is uniform. And then, the post-processing process. After the reaction, the product contains impurities and needs to be separated and purified. Commonly used distillation, extraction, filtration and other methods to obtain high-purity DBA in addition to unreacted raw materials, catalysts and by-products. Operation should be careful to avoid product loss or introduction of new impurities. Ultimately, safe production. During production, raw materials and products may be flammable and irritating. Operators should operate in accordance with regulations, wear protective equipment, ventilate the workshop well, and prepare fire extinguishing and first aid equipment to ensure personnel safety and smooth production.

Compared with other similar products, adipate dibutyrate (DBA) has the following advantages: First, DBA has good solubility. In many organic solvents, DBA can quickly dissolve and disperse evenly, just like a good wine melted in water, invisible but effective. In this way, when applied in coatings, inks and other fields, it can perfectly blend with other ingredients, making the product uniform in texture, smoother in application or printing, flat and flawless in coating or ink layer, ensuring the appearance and quality of the final product. Second, DBA has low volatility. Just like a calm person, it does not evaporate easily. This feature is extremely critical in industrial production, which can reduce the loss of raw materials caused by volatilization in the production process and reduce production costs. At the same time, because of its slow volatilization, it can reduce harmful gas emissions in the working environment, creating a healthier and safer working atmosphere for workers, in line with the current pursuit of environmental protection and occupational health. Third, DBA has excellent low temperature resistance. Like Aoxue Hanmei, it can still maintain good flexibility and plasticity even in low temperature environments. After adding DBA to plastic products and rubber products used in cold areas, it will not become hard and brittle due to low temperature, and can still maintain good physical properties, broadening the application range and application area of related products. Fourth, DBA has good compatibility with resin. It is like a confidant meeting and fits each other. In the production of plastic products, it can be closely combined with resin to enhance the comprehensive properties of plastic products, such as improving product strength, toughness, etc., so that the quality of plastic products is more reliable and durability is better.
