Triethylenetetramine, propoxylated (triethylene-tetramine adduct) is a clear yellow liquid with a vapour pressure of 1.1 x 10 -1Pa at 25 °C. It is neither highly flammable nor explosive or oxidizing. The auto-flammability was determined to be 344± 5 °C and the flash point is 167 ± 2°C. The water solubility was determined to be miscible with water in all proportions at 20.0 ± 0.5 °C, by visual assessment, using a flask method and has a pour point of <20 °C (<253 K). The boiling point was

240 to 410 °C (513 to 683 K) at 101.0 to 101.2 kPa the HPLC method is not applicable to determine the partition coefficient (log Pow) of substances of negative log10 therefore, it was decided to estimate the partition coefficient using a computer-based atom fragment contribution method, KOWWIN, version 1.68 (September 2010), © 2000 U.S. Environmental Protection Agency. The estimated partition coefficient (log10Pow) values for the three, main constituents were -2.74, -2.42 and -2.65.
