Aminoethylpiperazine-HP is available in bulk and in drums of 440 pounds (200 kilograms) net weight.

In order to maintain the high degree of purity with which aminoethylpiperazine-HP is manufactured and shipped, the following storage and handling considerations are recommended:

Dry Inert Gas Blanket

• This product should be stored under a dry inert gas blanket, such as nitrogen, to minimize contamination resulting from contact with air and water.

Materials of Construction

• If slight coloration of the ethyleneamine is acceptable, storage tanks may be made of carbon steel or black iron, provided they are free of rust and mill scale.
• However, if the amine is stored in such tanks, color may develop due to iron contamination.
• If iron contamination cannot be tolerated, tanks constructed of types 304 or 316 stainless steel should be used. (Note: Because they are quickly corroded by amines, do not use copper, copper alloys, brass, or bronze in tanks or lines.)

Storage Temperature

• Aminoethylpiperazine-HP has a freezing point of -17°C. To avoid freezing, the product should be maintained above this temperature.

Shelf Life

• The product should retain its conformance to sales specifications for a period of at least two years from date of manufacture if the product is stored at less than 100°F (37.8°C) in its undamaged, unopened, factory packaged container.
