Developing biotechnological methods to produce glycolic acid and alkyl glycolates requires knowledge of thermophysical and thermodynamic data. Vapor pressures of linear alkyl glycolates HO-CH2-COO-(CH2)(n)-H with n = 1-8 were determined by the transpiration method. Standard molar enthalpies of vaporization at experimental temperature and at 298.15 K were derived from the temperature dependence of the vapor pressure. The critical temperatures and pressures of alkyl glycolates were measured by the pulse-heating method. The experimental data were successfully checked for internal consistency. Molar heat capacity of atmospheric pressure for liquid esters was measured by the method of differential scanning calorimetry in the temperature range 303-423 K. The molar liquid heat capacities at 298.15 K and atmospheric pressure of alkyl glycolates were calculated from the result of this work. The measured values were used for estimating prediction capabilities of group-contribution methods by Constantinou and Gani, Marrero and Gani, and Hukkerikar et al. for critical properties and Chickos and Acree, Domalski and Hearing, and Ceriani et al. for heat capacity at 298.15 K. Results of this study could be used for the design and optimization of the chemical processes of the utilization of renewable feedstock.
