A Study on the Flash Point and Spontaneous Ignition Determination of Diethylene Glycol

Jung-Hun Kim, Jae-Wook Choi

Abstract

This study investigates the main factors of fire prevention, such as spontaneous ignition and flash point, while using Diehylene Glycol (DEG) as the antifreeze for automobile and industrial machines. Our results show the flash point of 142℃ and the minimum ignition temperature of 388℃ in the range of 130㎕～ 150㎕. By increasing temperature to ignite in 1 second, an instantaneous ignition temperature of the sample is 569℃ in the sample amount of 140㎕.
