What is dibutyl phthalate (DBP)?

Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9) 2, it is a colorless oil, although impurities often render commercial samples yellow.

What temperature is dibutyl phthalate (DBP)?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range.

Is dibutyl phthalate a high-priority substance?

EPA designated dibutyl phthalate (1,2-Benzene- dicarboxylic acid, 1,2- dibutyl ester) as a High-Priority Substance in December 2019 and the chemical is currently undergoing risk evaluation. Find other information about other chemicals undergoing risk evaluations under TSCA .

What is dibutyl phthalate used for?

The primary use for dibutyl phthalate is as a plasticizer, in adhesives and sealants, and paints and coatings. Information from the 2016 Chemical Data Reporting (CDR) for dibutyl phthalate indicates the reported production volume is between 1 million and 10 million lbs/year (manufacture and import).

What is monobutyl phthalate (MBP)?

Monobutyl phthalate (MBP) is its major metabolite. Biodegradation by microorganisms represents one route for remediation of DBP. For example, Enterobacter species can biodegrade municipal solid waste—where the DBP concentration can be observed at 1500 ppm—with a half-life of 2–3 hours.

What is DBP used for?

It has a boiling point of 340°C, flash point of 171°C, and is soluble in substances like water, alcohol, ether, acetone and benzene. Common applications of DBP include as a plasticizer in PVA emulsions, solvent for dyes and chemicals, and to prevent foaming in some industries. DIBUTYL PTHALATE. DBP Structural Formula PROPERTIES
