Abstract
The principal application of autoignition temperature (AIT) is to define the maximum acceptable surface temperature in a particular area, usually for electrical classification purpose. AIT is an important variable used to characterize the fire and explosion hazard of liquids and must be known for safe handling, storage, and transportation. In this work, the AITs of 1-pentanol and its binary mixtures with water are measured in compliance with the EN 14522:2005 and ASTM E659 method. The measured AITs are (288±1.5 °C, 298±1.5°C), and for 1-pentanol and 1-pentanol+water mixtures, respectively. It is found that the AIT reported in DIPPR 2012 and HCH is in the reproducibility, and the difference is up to 10 °C. The ISCS, SFPE, Merck reports the AIT beyond the reproducibility in with differences of 32 °C, 152 °C and 22 °C. Measured AIT of 1-pentanol conducted with 12% of water will result in a value higher than the one without water by 10 °C.
