The critical temperatures and critical pressures of six n-alkyl benzoates C6H5COO(CH2)nH with n ) 1 to 6 have been measured. All the substances are thermally unstable at their critical points. The method of pulse-heating of a wire probe placed into the liquid under study has been used. Residence times are from (0.03 to 1) ms, which results in little decomposition of the liquid in the course of measuring. The experimental critical properties of alkylbenzoates have been compared with the values estimated by the group contribution methods of Constantinou and Gani and Marrero and Gani.
