Critical temperatures and pressures of linear alk-1-enes with 13 to 20 carbon atoms using the pulse-heating technique

The paper presents experimental critical temperatures and critical pressures of thermally unstable alk-1-enes C_nH_2n with a number of carbon atoms n=13–20. The method of pulse heating of a wire probe placed in the liquid under investigation has been used. Equations for correlation of the critical temperatures and pressures of alk-1-enes with a number of carbon atoms in a molecule have been obtained. The acentric factors of alk-1-enes have been calculated.
