Features: Contains two hydroxyl groups and one amino group. Hydroxyl reduces the vapor pressure, increases the solubility, is conducive to the absorption of acid gas, and can increase the concentration, reduce circulation, and reduce energy consumption. The presence of the methyl group in the amino group reduces the alkalinity and activity of the amino group and reduces the CO2 absorption rate.
The molecular weight is 119.16, the melting point is -21°C, the flash point is 127°C, the freezing point is -21°C, and the refractive index is 1.4678. The viscosity (20°C) is 101 MPa·sec.
