Sulphuric acid is so strongly protogenic that most compounds of oxygen and nitrogen accept protons from it to some extent. Not only amines, but ethers and ketones, give twice the normal freezing point depression, suggesting that such reactions as... [Pg.202]

Commercial cyclohexanol contains a small percentage (less than 1%) of cyclohexanone and its freezing point is somewhat depressed from the reagent grade. Although cyclohexanone is slightly more volatile, the relative volatility is so small that losses of the ketone will not cause the freezing point to rise... [Pg.383]
