Resin
Tetraethylenepentamine (TEPA) is an important organic compound with the chemical formula C8H23N5, molecular weight of about 189.3, and CAS registry number 112-57-2. It is also known as tetraethylene pentamine, and its structural formula is H2N(CH2CH2NH)3CH2CH2NH2. As a member of the ethyleneamine series, tetraethylenepentamine plays an important role in industrial applications.
In terms of physical properties, TEPA is a yellow or orange-red viscous liquid at room temperature with hygroscopicity. The relative density of the pure product is 0.998 (20/20 degC), the melting point is about -30 degC to -40 degC, and the boiling point is about 333 degC to 340 degC. The refractive index is 1.5042 to 1.505, and the flash point is about 163 degC to 164 degC. The vapor pressure is less than 0.01 mmHg (20 degC) and the vapor density is 6.53 (relative to air). TEPA is readily soluble in water and most organic solvents such as ethanol, methanol and acetone, but is insoluble in benzene and diethyl ether. The water solubility is about 6540 g/L and the pH value is about 11.8 (20 g/L, H2O, 20 degC).
