N,N’-Bis(1-methylpropyl)-1,4-phenylenediamine / Antioxidant 44PD, Antioxidant 4720 Principal Use
1)High efficiency antioxidant of gasoline——much better than
Antioxidant T-501. Especially suitable for cracked or heating crack
gasoline additives.
2)Desulfurizer of gasoline——With the existance of air and water, 44PD can transform thioalcohol into bisulfides.
3)High efficiency antioxidant of vegetable oil
4)General type Antioxidant of natural rubber and synthetic rubber.
Note:
To achieve the?optimum performance of this product, the application
temperature should be between room temperature and 125℃. When it is used
for gasoline, the added amount should dependent on the content of
olefins and storage conditions, usual addition level is
0.001-0.01%。Cracked gasoline should be directly added at the
fractionation exit.
