DBP: 1. What are the properties of dibutyl phthalate (DBP)?

1. What are the properties of dibutyl phthalate (DBP)? DBP is an oily liquid that is soluble in fat and slightly soluble in water. It is not very volatile so does not vaporise readily into the atmosphere. Under the European Union classification system that applies to labelling of chemicals in commerce, it is classified as “dangerous to the environment” (very toxic to aquatic organism).

In this work, the photocatalytic degradation properties of dibutyl phthalate (DBP) were investigated using α-Fe 2 O 3 nanoparticles and H 2 O 2 in aqueous solution system. The optimal parameters and mechanism of degradation were discussed by changing the morphology and usage amount of catalysts, the dosage of H 2 O 2, pH value and the initial

Dibutyl phthalate | C16H22O4 - PubChem

Dibutyl phthalate is 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.Although used extensively as a plasticiser, it is a ubiquitous environmental contaminant that poses a risk to humans.

Dibutyl phthalate (DBP) is a ubiquitous soil contaminant. We have investigated the sorption, degradation and residue of DBP in 20 types of agricultural soils and aimed to identify the major soil properties that dominate the fate of DBP. Sorption isotherms of DBP in all soils were fitted well with the Freundlich model.

If the adsorption of DBP onto a freshly created bubble surface was assumed to be diffusion-controlled (i.e., the kinetic transfer rate is much faster than the bulk diffusion rate), the dynamic ST data in Fig. 1 can be used to determine the diffusivity of DBP in an aqueous static bulk phase. The set of model parameter obtained from the best-fit between equilibrium ST data and model prediction ...
