  • What is problem 1 of dibutyl phthalate?
  • Problem 1 Dibutyl phthalate (DBP), a plasticizer, has a potential market of 12 million Ib/year (AZChE Student Contest Problem) and is to be produced by reaction of n-butanol with monobutyl phthalate (MBP). The reaction follows an elementary rate law and is catalyzed by H2SO4.
  • 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.
  • What is the reaction between MBP and butanol?
  • The reaction follows an elementary rate law and is catalyzed by H2SO4. A stream containing MBP and butanol is to be mixed with the H2SO4 catalyst immediately before the stream enters the reactor. The concentration of MBP in the stream entering the reactor is 0.2 lb mol/ft3 and the molar feed rate of butanol is five times that of MBP.
