Chemical nature: Forbidden qualitative: strong oxidizing agent, strong reducing agent, strong acid, strong base. Ecological nature: Ecotoxicity EC50: 1.2 ~ 1.51mg / L (luminous bacteria, microtox toxicity test) Biodegradability Miti-I test, initial concentration of 100 mg / L, sludge concentration 30 mg / L, 2 weeks later degraded 77%. Non-biodegradability In the air, when the hydroxyl radical concentration is 5.00 × 105 / cm3, the degradation of the half-life is 7.8d (theory). Other harmful effects The material is damaged by the environment and should pay spe

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.
