VLE data for water - glycerol mixtures

 The purpose of this post is to come up with reliable data for the vapor-liquid equilibrium (VLE) of solutions made of water and glycerol ($C_3H_8O_3$). Notice that in this case the component of interest is water!. The data presented below was extracted from the paper of David H. T. Chen and A. Ralph Thompson in 1970.

The experiments of Chen and Thompson were performed at a pressure of $760 mmHg$. The data was extracted from Table III in Chen and Thompson's paper. These data were obtained as follows: the raw data were processed to get a fitting curve. From this process, a function representing that curve was also, presumably,  obtained, from which the data in Table III followed.
