Antioxidant 44PD Applications
1) Efficient gasoline antioxidant and anti-adhesive agent - far more effective than the commonly used T-501 antioxidant. N,N'-disecbutyl-p-phenylendiamine is especially suitable as an additive for cracking or thermal cracking gasoline (gasoline with high olefin content). Antioxidant 4720 can effectively prevent the oxidation of olefins to produce gel, thereby avoiding the production of carbon deposits in the combustion chamber, piston top, cylinder head and other parts during the use of the oil. Compared with amine antioxidants, Antioxidant 44PD has less dosage and better antioxidant effect, which greatly reduces environmental pollution. 2) Gasoline demercaptan agent - In the presence of air and water, Antioxidant 44PD acts as a catalyst to convert mercaptans into disulfides. Since in this process, Antioxidant 4720 is only a catalyst, and N,N'-Bis(1-methylpropyl)-1,4-benzenediamine itself is not soluble in alkali, so after subsequent After the alkali removal operation, AO-44PD still remains in the gasoline, and the antioxidant efficiency is not affected at all. 3) Antioxidant 4720 is vegetable oil special antioxidant. 4) Antioxidant 44PD CASNo 101-96-2 is an universal antioxidant for natural rubber and synthetic rubber.
