Properties: colorless to pale yellow transparent viscous liquid, slightly ammonia flavored, when low temperature become colorless to yellowish cubic crystal system crystal;
Solubility: soluble in water, ethanol, acetone, glycerin, glycol, etc., slightly soluble in benzene, ether, and carbon tetrachloride, and almost insoluble in nonpolar solvents;
Features: when exposed to air, the color becomes deeper, irritating, hygroscopic, and can absorb acid gases, such as carbon dioxide and hydrogen sulfide;
Chemical property:
The alkalinity of triethanolamine is weaker than ammonia (pKa7.*2), with the properties of tertiary amines and alcohols;
