Autoignition temperature describes the minimum temperature to which a substance must be heated, without the application of a flame or spark, which will cause that substance to ignite. The lower the ignition temperature, the greater the potential for a fire started by typical laboratory equipment. For the smaller hydrocarbons the autoignition temperature is inversely related to molecular weight, but it also increases with carbon chain branching. The measurement AIT is dependent upon many factors, namely initial temperature, pressure, volume, fuel/air stoichiometry, catalyst material, concentration of vapor, ignition delay. The objective of this study is to derive empirical equation to estimate the AIT of alcohol compounds from the normal boiling points and molecular weights. |
