Dibutyl Phthalate Introduction
Dibutyl Phthalate (DBP) is a colorless oily liquid, with a sticky texture and special odor. It uses phthalic anhydride and butanol as raw materials. The physical properties are as follows: melting point 3.5 ℃ (below freezing point), boiling point 340 ℃ (requiring high-temperature evaporation), density 1.045g/mL (slightly higher than water). Dibutyl Phthalate is difficult to dissolve in water, but easily soluble in organic solvents such as alcohol and ether. DBP is a typical ester compound and a widely used general-purpose plasticizer in industrial production and laboratory research. Its unique molecular structure endows it with excellent plasticizing properties, compatibility, and processing adaptability.
As an efficient plasticizer, DBP is mainly used for the modification of materials such as polyvinyl chloride (PVC), cellulose esters, and natural rubber. Through intermolecular forces, it can effectively improve the flexibility and cold resistance of materials. DBP is commonly used in products such as rain gear and flexible parts of toys. In the industrial field, DBP can also be used as a solvent for nail polish (to enhance color persistence), medical devices (blood bags, artificial heart casting films), paints, adhesives and other products.
Dibutyl Phthalate is usually packed in iron drums and IBC drums. It should be stored in a cool, ventilated warehouse and separated from oxidants and acids. Also, DBP should be away from fire and heat sources. Its UN NO. is 3082.
