Definitions

  • Representative monohydric alcohols include, methanol, ethanol, propanol, butanol, benzyl alcohol, and the like as well as other higher molecular weight alcohols.
  • Suitable polyhydric alcohols typically contain about 2 to about 10 hydroxyl groups.
  • Representative polyhydric alcohols include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol, tripropylene glycol, glycerol, pentaerythritol, erythritol, sorbitol, mannitol, and the like and sugars such as glucose, galactose and other carbohydrates.
  • Representative aromatic hydroxyl compounds include phenols, napthols, and the like.
  • a mixture of polyisobutenyl succinic anhydride (Mw 1000, 50.3 g, Oronite OLOA-15500, Oronite Company LLC, Oronite Additive Division, Belle Chasse, La.), pentaerythritol (5.1 g) containing catalytic amount (0.5 g) of p-TSA is heated to 200° C. with stirring under a constant stream of N 2 gas.
  • the esterification is monitored by disappearance of anhydride peak and appearance of ester peak in the IR.
  • the water formed in the reaction is collected in a Dean Stark.
  • the reaction went to completion after 90 minutes at this temperature.
  • the reaction mixture is cooled to 150° C. and heavy aromatic naphtha (124 g) is added to dilute the product.
  • the unreacted pentaerythritol is removed by filtration through celite.
  • the clear amber colored product is collected for blending with the metal deactivator to make the inhibitor for fuel stability testing.
