Dibutyl phthalate
DBP is produced by the reaction of n -butanol with phthalic anhydride. [3] DBP is an important plasticizer that enhances the utility of some major engineering plastics, such as PVC. Such modified PVC is widely used in plumbing for carrying sewerage and other corrosive materials. [3] Degradation [ edit]
Phthalate Di-butyl phthalate - GreenFacts
DBP is a phthalate with the same core structure as DIDP and DINP but with two shorter side chains attached, each having four carbon atoms. It is an oily liquid that is soluble in fat and to some extent in water. More... The same information on Level 1: Summary Level 2: Details Level 3: Source 2. How is DBP used?

Over 75% of DBP is used as a plasticizer in polymers such as PVC, 14% is used in adhesives, 7% in printing inks and 3% in other miscellaneous uses, including sealants and grouting agents used in construction as well as consumer products such as cosmetics.

DBP: 1. What are the properties of dibutyl phthalate (DBP)? - GreenFacts
Level 1: Summary Level 2: Details Level 3: Source 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.
- How is di-n-butyl phthalate (DBP) produced?
- DBP is produced by the reaction of phthalic anhydride with n-butanol in the presence of concentrated sulphuric acid as a catalyst. Excess alcohol is recovered and recycled and the di-n-butyl phthalate is purified by vacuum distillation and/or activated charcoal.
- What is DBP used for?
- Production has been steadily decreasing during the 1990’s. Over 75% of DBP is used as a plasticizer in polymers such as PVC, 14% is used in adhesives, 7% in printing inks and 3% in other miscellaneous uses, including sealants and grouting agents used in construction as well as consumer products such as cosmetics.
- What is DBP made of?
- DBP is produced by esterifying Butanol and Phthalic Anhydride.excellent compatibility with PVC and has high plasticizing efficiency.
- How much phthalic anhydride (DBP) is produced a year?
- There is a clear decreasing trend in the production of DBP: 49,000 t/a (1994) – 37,000 t/a (1997) – 26,000 t/a (1998). The production (>1,000 tonnes) of DBP in 1998 was located at three production sites in the EU. DBP is produced by the reaction of phthalic anhydride with n-butanol in the presence of concentrated sulphuric acid as a catalyst.
- How many producers of DBP are there in the EU?
- There are currently 3 producers of DBP in the European Union. The estimated production in the European Union was around 26 000 tonnes in 1998, over two-thirds of which was used in the EU. Production has been steadily decreasing during the 1990’s.
- What is DBP & phthalic anhydride?
- DBP is produced by esterifying Butanol and Phthalic Anhydride. excellent compatibility with PVC and has high plasticizing efficiency. a considerable low dosage is enough to reach satisfactory flexibility. a primary plasticizer for general purpose and often used as gelation agent.
