ABSTRACT
The solubilities of triethylenediamine in methanol, ethanol, isopropanol, I-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 greater than ethanolgreater than isopropanol greater than I-butanol greater than ethyl acetate. An empirical equation was proposed and verified by experimental solubility data.
