  • What is di-2-propylheptyl phthalate (DPHP)?
  • Di (2-propylheptyl) phthalate, commonly referred to as DPHP, stands as a pivotal component in polymer production. Primarily employed as a plasticizer, DPHP plays a fundamental role in enhancing the properties of polyvinyl chloride (PVC) and other copolymers.
  • How effective is diheptyl phthalate?
  • Results of kinetic experiments indicated that diheptyl phthalate (DHpP) was adsorbed most efficiently (3.21 mg/g) ... It was concluded that the application of low cost alpha-CD-linked chitosan bead could have the potential to effectively remove PAEs from different aquatic environments.
  • What is Diisoheptyl phthalate?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
  • ) Diisoheptyl phthalate is a phthalate used as a plasticizer. Diisoheptyl phthalate is typically a mixture of chemical compounds consisting of various isoheptyl esters of phthalic acid with the chemical formula C 22 H 34 O 4.
  • What is the EPA contract for diheptyl phthalate?
  • EPA Contract No. 68-02-4254. Menlo Park, CA: SRI International (1987) (3) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. Washington, DC: Amer Chem Soc pp. 7-4, 7-5, 8-12 (1990) BCFs of 0.9 to 2.2 and 6.2 to 16.7 were measured for diheptyl phthalate in carp at chemical concentrations of 1 and 0.1 mg/L, respectively (1).
  • Does diheptyl phthalate have chromophores?
  • Diheptyl phthalate does contain chromophores that absorb at wavelengths >290 nm (3) and therefore may be susceptible to direct photolysis by sunlight (SRC).

  • Is diheptyl phthalate immobile in soil?
  • Using a structure estimation method based on molecular connectivity indices (1), the Koc of diheptyl phthalate can be estimated to be 5.7X10+4 (SRC). According to a classification scheme (2), this estimated Koc value suggests that diheptyl phthalate is expected to be immobile in soil.
