Pentaerythritol (PENTA)

PENTA process:

  • Acetaldehyde and Formaldehyde solution react in a continuous process in a first step under alkaline conditions (Aldol Condensation) and in a second reaction step it reacts with formaldehyde (Cannizzaro Reaction) to complete the synthesis of Penta
  • The reaction product is fed to a continuous crystallization unit
  • Di-Pentaerythritol can also be produced as secondary product
  • Sodium Formate is formed as a by-product
  • Key features of the continuous process are:
    • low formation of unwanted by-products
    • low and constant utility demand
    • excellent operation results in small apparatuses
