Alternative Title
Experimental Study According to the Mixing Ratio of Ethanol and Dipropylene Glycol monomethyl ether on AutoIgnition of Diffuser
Abstract
In this study, the minimum autoignition temperature and ignition delay time were measured by varying the mixing ratio of ethanol and DPM(Dipropylene glycol monomethyl ether), which are mainly used as a diffuser solvent, using the minimum autoignition temperature measuring device of ASTM E 659. In addition, the ignition characteristics were identified by obtaining the activation energy.
