Ph of polyethylene glycol
Webb8 juni 2007 · A convenient calibration method for pH measurements in monoethylene glycol (MEG) + water solvents is described. The calibration has to be performed once for each electrode type. pH measurements were performed in CO 2 (g, ∼1 bar)-saturated solutions of 60 and 90 wt % MEG at 4−80 °C with varying NaHCO 3 and KHCO 3 contents.
