HF is that it attacks glass, so containers must be made of some inert material such as Tefl on, a polytetrafl
uoroethylene. The data for this nonaqueous solvent are shown in Table 10.4 . As expected from the
rather high heat of vaporization (which lies between the values for water and liquid ammonia) liquid
HF has a liquid range that spans over 100°C and a relatively high boiling point.
