Air & Water Reactions
Insoluble in water.
Wash DBP with H2O (to free it from alcohol), then dilute NaOH (to remove any butyl hydrogen phthalate or acid), aqueous NaHCO3 (charcoal), then distilled water. Dry it (CaCl2), distil it at 10torr or less, and store it in a desiccator over P2O5. [Beilstein 9 II 586, 9 III 4102, 9 IV 3175.]
A phthalate metabolite with genotoxic effect.
Dibutyl phthalate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Avoid contact with strong oxidizing agents and strong bases. Will not polymerize. [USCG, 1999]. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].
Plasticizer; solvent for oil-soluble dyes, insecticides and other organics; antifoam agent; textile fiber lubricant; fragrance fixative; insect repellent.
ChEBI: A phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of butan-1-ol.
Dibutyl phthalate is a colorless oily liquid. Dibutyl phthalate is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Dibutyl phthalate is a liquid Dibutyl phthalate can easily penetrate the soil and contaminate groundwater and nearby streams. Dibutyl phthalate is combustible though Dibutyl phthalate may take some effort to ignite. Dibutyl phthalate is used in paints and plastics and as a reaction media for chemical reactions.
It is mainly used as a nonreactive epoxy diluent.
