Conclusions:
The vapor pressure of 2,3-dimethylphenol at various temperatures using ebulliometry. The experimental vapor pressure at 196 deg C was 59995 Pa
Executive summary:

The vapor pressure of 2,3-dimethylphenol at various temperatures using ebulliometry. The experimental vapor pressure at 196 deg C was 59995 Pa and 101325 Pa at 219 deg C.

The vapor pressure at 219 deg C was 101325 Pa (i.e atmospheric pressure), which indicates that the boiling point of 2,3 -dimethyl phenol was 219 deg C.
