Dibutyl Phthalate (DBP) is a chemical compound whose fundamental properties are key to its widespread industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. offers a closer look at the chemistry behind DBP, including its molecular structure, physical characteristics, and typical manufacturing methods.

Chemically, Dibutyl Phthalate is an ester of phthalic acid, with the molecular formula C16H22O4. Its structure consists of a benzene ring with two ester groups, each attached to a butyl chain. This specific molecular configuration grants DBP its characteristic properties as a plasticizer and solvent. Its physical form is typically a colorless to faint yellow oily liquid, with a very mild aromatic odor. The high purity, often exceeding 99%, ensures minimal impurities that could interfere with its intended functions.

The physical properties of Dibutyl Phthalate are crucial for its industrial utility. It exhibits a low melting point of around -35°C and a high boiling point of approximately 340°C, indicating a wide liquid range. DBP is soluble in most organic solvents like alcohol, ether, and benzene, but only slightly soluble in water. This solubility profile dictates its use in various formulations and its behavior in environmental contexts.

The manufacturing of Dibutyl Phthalate typically involves the esterification reaction between phthalic anhydride and n-butanol. This process, often catalyzed by acids, produces DBP along with water. Subsequent purification steps, such as vacuum distillation, are employed to achieve the high purity required for industrial markets. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict manufacturing and quality control protocols to ensure the consistent production of premium Dibutyl Phthalate.
