Solubility of Triethylenediamine in Methanol, Ethanol, Isopropanol, 1-Butanol, and Ethyl Acetate between 276.15 K and 363.15 K

The solubilities of triethylenediamine in methanol, ethanol, isopropanol, 1-butanol, and ethyl acetate between 276.15 K and 363.15 K were measured using a synthetic method at atmospheric pressure. A laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The solubility of triethylenediamine in the above solvents increased in the order methanol > ethanol > isopropanol > 1-butanol > ethyl acetate. An empirical equation was proposed and verified by experimental solubility data.
