Dibutyl phthalate
Infobox references. 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 commercial samples are often yellow. [3]
Dibutyl Phthalate - an overview | ScienceDirect Topics
Dibutyl phthalate can be used as a plasticizer in nitrocellulose lacquers, elastomers, explosives, nail polish, and solid rocket propellants. Other uses include perfume fixative, textile lubricating agent, safety glass additive, printing inks, and adhesives. View chapter Purchase book Phthalates

Risk Evaluation for Dibutyl Phthalate (1,2-Benzene
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). Conditions of Use of Dibutyl Phathlate
- What is dibutyl phthalate (DBP)?
- N verify (what is YN ?
- ) 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 is dibutyl phthalate used for?
- It has been used in insect repellents and as a solvent for perfume oil and resins. Dibutyl phthalate can be used as a plasticizer in nitrocellulose lacquers, elastomers, explosives, nail polish, and solid rocket propellants. Other uses include perfume fixative, textile lubricating agent, safety glass additive, printing inks, and adhesives.
- Is dibutyl phthalate a teratogen?
- Dibutyl phthalate (DBP) is one of the six phthalic acid esters found on the Priority Pollutant List, which consists of pollutants regulated by the United States Environmental Protection Agency (U.S. EPA). DBP was added to the California Proposition 65 (1986) list of suspected teratogens in November 2006.
- 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.
- Can microorganisms biodegrade dimethyl phthalate?
- 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. In contrast, the same species can break down 100% of dimethyl phthalate after a span of six days.
- What happens when DBP is added to PVC-Li 2 b 4 O 7?
- Upon addition of DBP, there is the formation of a new peak which assigned as C = O stretching mode at 1,728 cm −1 as shown in Fig. 2b, c. Figure 2b, c indicate that the peak at 1,734 cm −1 for DBP is shifted to 1,728 cm −1 for SPE4 and SPE7, respectively. This is evidence of complexation between PVC–Li 2 B 4 O 7 and DBP.
