Abstract:

The study reported is a theoretical and experimental investigation of the relationship between the lower ignition limit of organic substances, such as alkanes, alcohols and esters, and the number of carbon atoms in their molecules. The overAUTHORS DERIVED THE FOLLOWING EQUATION FOR THIS RELATIONSHIP IN GASEOUS MIXTURES WITH AIR Climit is equivalent to 1an-1td, where climit is the concentration of the combustible at the lower limit of the ignition n is the number of carbon atoms in the molecule of the combustible and a and d are constants which are characteristic for the given combustible and the conditions of the experiment. This equation expresses the hyperbolic relationship of both parameters. The experimental study, conducted on alkanes from methane to octane, alcohols from methanol to nonanol, and esters formiates and acetates with alkyls from methyl to nonyl, confirmed the validity of the equation and made it possible to determine the numerical values of the constants, which remain the same in the homologue series.
