Special Hazards of Combustion Products: Toxic fumes of NO x | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. | [Shipping]

N-Aminoethypiperazine is a combustible and corrosive aliphatic amine It is a colorless to light yellow liquid | [Chemical Properties]
viscous light yellow liquid | [Uses]
1-(2-Aminoethyl)piperazine is utilized in a variety of reactions for studying corrosion inhibition, biological activity and metal ligand effects on catalysis. It is used for epoxy curing, surface activation, and as an asphalt additive. It is used in lube oil and fuel additives, mineral processing aids, polyamide resins, urethane chemicals, wet strength resins. | [Uses]
Used for studying corrosion inhibition | [Preparation]
he synthesis of N-(2-aminoethyl) piperazine from PZ and MEA in the presence of CO2 was conducted using a method similar to that of thermal degradation experiments. 7 m PZ/2 m MEA with 0.3 mol CO2 /mol alkalinity was placed in ?-inch OD 316 stainless steel thermal cylinders , which were then sealed and placed in a convection oven held at 150 °C. Cylinders were removed periodically and samples were analyzed using ion chromatography. | [Flammability and Explosibility]
