Extract

The literature of the sugars would appear to show that no sugars have hitherto been observed to sublime with the exception of glycolose, CH2OH CHO, which is described as being “perceptibly volatile with water and alcohol vapour under diminished pressure, especially from a pure, concentrated solution” (Lippmann, Chemie der Zuckerarten, p. 4). This substance, being the first of the sugar series, might be expected to have properties somewhat different from the other members of the series, which are usually looked upon as non-volatile. Experiments with rhamnose and fructose appear to show that under diminished pressure they do sublime.
