REACH Phthalates Regulations Amended to Apply to All
DIBP has been widely used as a substitute to DBP to negate the existing restrictions under Annex XVII for the manufacture of products such as PVC, rubber, fiberglass and plastic products, especially in Australia, where DIBP is imported predominantly for the production of PVC and rubber.
1 June 2009 Background document for dibutyl phthalate (DBP)
It appears that, following the classification of DBP as Toxic to reproduction (Cat. 2), DBP has already been replaced by alternative substances for many applications, which is reflected in the steep decline in the total consumption of the substance as described in the section 2.2.1.

The team prepared three different DBP-based building blocks, with either 2,7-substitution (MeDBP and PhDBP) or 5,10-substitution (DBP-Ph) for the linking sites. These building blocks were linked using triformylbenzene (TFB) or triformylphloroglucinol (TFP) in solvothermal syntheses.
Dibutyl phthalate
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] Production and use [ edit]
ANALYSIS OF ALTERNATIVES and SOCIO-ECONOMIC ANALYSIS Public
Indeed, at the time of submission (in 2013) AVX was in the process of attempting to substitute DBP with a separately identified potential alternative. Although this effort was ultimately unsuccessful, it nonetheless demonstrates AVX’s hard work on the substitution of DBP.
- How can we quantify the bromine substitution during DBP formation?
- Researchers have developed indices to help quantify the bromine substitution during DBP formation. Bromine incorporation factor (BIF) was introduced by Gould et al. (1983) to investigate the bromine substitution degree of THMs.
- What is the difference between bromine substitution in Dhaas and THMs?
- Their study results showed that bromine substitution in DHAAs and THMs were comparable whereas bromine substitution in THAAs and DHANs tended to be 10% lower and 60% higher than THMs, respectively.
- What is BSF in DBP?
- The BSF is defined as the ratio of the molar concentration of bromine incorporated into a given class of DBP to the total molar concentration of chlorine and bromine in that class (Equation (2) ). The BSF is the percentage of bromine in the total halogen of each class of DBP and it can vary from 0 to 1.
