| Abstract: | This work introduces a novel, reliable and
simple correlation for predicting the flash point of various types of saturated
and unsaturated hydrocarbons containing cyclic and acyclic paraffins, olefins,
alkynes and aromatic hydrocarbons. It is shown that the new method is based on
the number of carbon and hydrogen atoms and some specific molecular moieties,
which can easily be used for any types of hydrocarbons. The largest available
experimental data consisting of 441 diverse hydrocarbons are used here in order
to derive and test the general correlation. For a data set containing 423 of
these
441 hydrocarbons, the root mean square (rms) and average absolute deviations
are 7.7 and 5.7 K, respectively. The estimated flash points for 18 further hydrocarbons
containing complex molecular structures have been compared with one of the best
available new group additivity methods, which give much lower values of the rms
and average absolute deviations. |
