Typical Value, Units
Melting Point, Final
• 4-ADPA, as a chemical intermediate, is used in the manufacture of aniline type dyes. • 4-ADPA may be used as an antioxidant in certain fuels and as a component in lubricant additives. • Antidegradants manufactured from 4-ADPA are used in both the rubber and fuels industry.
Storage and Shelf Life
For bulk storage, 4-ADPA should be maintained at 85-95°C under a nitrogen blanket. For shipment in isotanks, trucks and rail cars, 4-ADPA can be allowed to solidify. The container should be kept under a nitrogen blanket with enough initial pressure to avoid a vacuum from cooling and solidification of the 4-ADPA. Remelting of the 4-ADPA to 90°C can be done with either 40 psig or 3 barg steam and should be done with nitrogen blanketing supplied to the container. If it is desired to keep 4-ADPA molten during shipment, then the conditions above for bulk storage should be used. The shelf life of 4-ADPA is 24 months from the date of manufacture, based on the recommended handling and storage conditions. Once the material has surpassed shelf life, please contact us if you would like to receive our suggestions for material re-verification, based on key product characteristics.
