  • What is dibutyl phthalate (DBP)?
  • Transcribed Image Text: Dibutyl phthalate (DBP), a plasticizer, has a potential market of 12 million lbm/yr (AICHE Student Contest Problem) and is to be produced by reaction of n-butanol with monobutyl phthalate (MPB). The reaction follows an elementary rate law and is catalyzed by Hâ‚‚SO4.
  • Is dibutyl phthalate used as a plasticizer?
  • Plasticizers are chemical additives that improve the plasticity of a polymer and are widely used, including in food packaging materials. One common phthalate plasticizer is dibutyl phthalate (DBP). A method to detect the presence of DBP in food samples is urgently needed.
  • Is DBP a plasticizer?
  • DBP has a low vapor pressure of 2.67 x 10 −3 Pa. Thus DBP does not evaporate readily (hence its utility as a plasticizer). The Henry's Law constant is 8.83 x 10 −7 atm-m 3 /mol. DBP is regarded as an endocrine disruptor.
  • What is the reaction between n-butanol and monobutyl phthalate?
  • The reaction between n-butanol and monobutyl phthalate to produce dibutyl phthalate can be represented by the following balanced chemical equation: C4H9OH + C6H4 (CO2CH3)CO2C4H9 → C6H4 (CO2C4H9)2 + H2O Step 2: Calculate the molar feed rate of butanol.
