Molecular Formula H2NCH2CH2OH CAS No. 141-43-5 nature of ammonia molecules of hydrogen hydroxyethyl -CH2CH2OH was replaced by a generation of compounds, can be divided into a triethanolamine, diethanolamine and triethanolamine. Often referred to a triethanolamine triethanolamine. One, two, three ethanolamine at room temperature are colorless and transparent liquid viscosity; There hygroscopicity and ammonia smell; With water, ethanol and acetone, etc. Compatibility slightly soluble in ether and carbon tetrachloride; Able to absorb carbon dioxide and hydrogen sulfide; With inorganic acid and organic acid ester produced by the reaction; Both parties alkaline. Triethanolamine the main physical constants are as follows : 10.5 ° C melting point. The boiling point of 170 ° C. The relative density of 1.0180 (20 / 4 ° C). Dynamic viscosity (20 ° C) 24.14mPa s. A flash point of 93.3 ° C ND refractive index (20 ° C) 1.4540. 25 ° C benzene in the solubility of 1.4% ether in the solubility of 2.1%, the solubility of carbon tetrachloride to 0.2%. uses for acid gas and oil absorbent additives intermediates, also used pesticides, toxic medicine ethanolamine with the dilute solution very weak alkaline and irritating, with the increase of its concentration, eye, skin and mucous membrane irritant. Mouse oral LD50 of 700mg/kg, rat oral LD50 of 2100mg/kg. Operating scene maximum allowable concentration MAC. Operators should wear protective equipment. Within splash pleasant to the eye, should promptly wash with water more than 15 minutes and, if necessary, seek the advice of the doctors. Operating establishments should maintain good ventilation. packaging and storing plastic barrels or new packaging iron barrel, respectively (200 ± 0.5) kg or (180 ± 0.5) kg two, each consisting of a barrel average weighing up to 200 or 180kg. Industrial ethanolamine should be stored in clean, cool dry ventilated warehouse, in the transport process should be leakproof, fire, moisture.
