Dibutyl phthalate (DBP) is an organic compound with the chemical formula C16H22O4. It is a colorless, transparent, oily liquid with an aromatic odor. It is an important plasticizer and is widely used in industries such as plastics, rubber, and paint to give products good softness. The preparation of dibutyl phthalate is usually prepared by esterification reaction with phthalic acid and n-butanol as raw materials under the action of sulfuric acid catalyst.
The physical properties of dibutyl phthalate include insolubility in water, but easy solubility in organic solvents such as ethanol, ether, acetone, and benzene. It has a melting point of -35°C, a boiling point of up to 340°C, and a density between 1.044 and 1.048 g/cm3 at 20°C. This compound is particularly important in polyvinyl chloride processing because it can provide good solvency, thereby giving the products the required softness and elasticity. In addition, dibutyl phthalate is also used to make paints, adhesives, artificial leather, printing inks, safety glass, dyes, pesticides, fragrance solvents, fabric lubricants, etc.
Although dibutyl phthalate has a wide range of applications, it is also necessary to pay attention to its potential risks and hazards when using it. In future development, research and management on its safe use need to be strengthened to ensure its sustainable development for the human body and the environment. In addition, the impact of dibutyl phthalate on the environment is also worthy of attention. The threshold concentration that the most sensitive person can smell is 0.00026mg/L12.
